+
+	# with switches, installs modules with extra behavior

+
+=head1 DESCRIPTION
+
+This script provides a command interface (not a shell) to CPAN. At the
+moment it uses CPAN.pm to do the work, but it is not a one-shot command
+runner for CPAN.pm.
+
+=head2 Options
+
+=over 4
+
+=item -a
+
+Creates a CPAN.pm autobundle with CPAN::Shell->autobundle.
+
+=item -A module [ module ... ]
+
+Shows the primary maintainers for the specified modules.
+
+=item -c module
+
+Runs a `make clean` in the specified module's directories.
+
+=item -C module [ module ... ]
+
+Show the F<Changes> files for the specified modules
+
+=item -D module [ module ... ]
+
+Show the module details. This prints one line for each out-of-date module
+(meaning, modules locally installed but have newer versions on CPAN).
+Each line has three columns: module name, local version, and CPAN
+version.
+
+=item -f
+
+Force the specified action, when it normally would have failed. Use this
+to install a module even if its tests fail. When you use this option,
+-i is not optional for installing a module when you need to force it:
+
+	% cpan -f -i Module::Foo
+
+=item -F
+
+Turn off CPAN.pm's attempts to lock anything. You should be careful with
+this since you might end up with multiple scripts trying to muck in the
+same directory. This isn't so much of a concern if you're loading a special
+config with C<-j>, and that config sets up its own work directories.
+
+=item -g module [ module ... ]
+
+Downloads to the current directory the latest distribution of the module.
+
+=item -G module [ module ... ]
+
+UNIMPLEMENTED
+
+Download to the current directory the latest distribution of the
+modules, unpack each distribution, and create a git repository for each
+distribution.
+
+If you want this feature, check out Yanick Champoux's C<Git::CPAN::Patch>
+distribution.
+
+=item -h
+
+Print a help message and exit. When you specify C<-h>, it ignores all
+of the other options and arguments.
+
+=item -i module [ module ... ]
+
+Install the specified modules. With no other switches, this switch
+is implied.
+
+=item -I
+
+Load C<local::lib> (think like C<-I> for loading lib paths). Too bad
+C<-l> was already taken.
+
+=item -j Config.pm
+
+Load the file that has the CPAN configuration data. This should have the
+same format as the standard F<CPAN/Config.pm> file, which defines
+C<$CPAN::Config> as an anonymous hash.
+
+=item -J
+
+Dump the configuration in the same format that CPAN.pm uses. This is useful
+for checking the configuration as well as using the dump as a starting point
+for a new, custom configuration.
+
+=item -l
+
+List all installed modules with their versions
+
+=item -L author [ author ... ]
+
+List the modules by the specified authors.
+
+=item -m
+
+Make the specified modules.
+
+=item -M mirror1,mirror2,...
+
+A comma-separated list of mirrors to use for just this run. The C<-P>
+option can find them for you automatically.
+
+=item -n
+
+Do a dry run, but don't actually install anything. (unimplemented)
+
+=item -O
+
+Show the out-of-date modules.
+
+=item -p
+
+Ping the configured mirrors and print a report
+
+=item -P
+
+Find the best mirrors you could be using and use them for the current
+session.
+
+=item -r
+
+Recompiles dynamically loaded modules with CPAN::Shell->recompile.
+
+=item -s
+
+Drop in the CPAN.pm shell. This command does this automatically if you don't
+specify any arguments.
+
+=item -t module [ module ... ]
+
+Run a `make test` on the specified modules.
+
+=item -T
+
+Do not test modules. Simply install them.
+
+=item -u
+
+Upgrade all installed modules. Blindly doing this can really break things,
+so keep a backup.
+
+=item -v
+
+Print the script version and CPAN.pm version then exit.
+
+=item -V
+
+Print detailed information about the cpan client.
+
+=item -w
+
+UNIMPLEMENTED
+
+Turn on cpan warnings. This checks various things, like directory permissions,
+and tells you about problems you might have.
+
+=item -x module [ module ... ]
+
+Find close matches to the named modules that you think you might have
+mistyped. This requires the optional installation of Text::Levenshtein or
+Text::Levenshtein::Damerau.
+
+=item -X
+
+Dump all the namespaces to standard output.
+
+=back
+
+=head2 Examples
+
+	# print a help message
+	cpan -h
+
+	# print the version numbers
+	cpan -v
+
+	# create an autobundle
+	cpan -a
+
+	# recompile modules
+	cpan -r
+
+	# upgrade all installed modules
+	cpan -u
+
+	# install modules ( sole -i is optional )
+	cpan -i Netscape::Booksmarks Business::ISBN
+
+	# force install modules ( must use -i )
+	cpan -fi CGI::Minimal URI
+
+	# install modules but without testing them
+	cpan -Ti CGI::Minimal URI
+
+=head2 Environment variables
+
+There are several components in CPAN.pm that use environment variables.
+The build tools, L<ExtUtils::MakeMaker> and L<Module::Build> use some,
+while others matter to the levels above them. Some of these are specified
+by the Perl Toolchain Gang:
+
+Lancaster Concensus: L<https://github.com/Perl-Toolchain-Gang/toolchain-site/blob/master/lancaster-consensus.md>
+
+Oslo Concensus: L<https://github.com/Perl-Toolchain-Gang/toolchain-site/blob/master/oslo-consensus.md>
+
+=over 4
+
+=item NONINTERACTIVE_TESTING
+
+Assume no one is paying attention and skips prompts for distributions
+that do that correctly. C<cpan(1)> sets this to C<1> unless it already
+has a value (even if that value is false).
+
+=item PERL_MM_USE_DEFAULT
+
+Use the default answer for a prompted questions. C<cpan(1)> sets this
+to C<1> unless it already has a value (even if that value is false).
+
+=item CPAN_OPTS
+
+As with C<PERL5OPT>, a string of additional C<cpan(1)> options to
+add to those you specify on the command line.
+
+=item CPANSCRIPT_LOGLEVEL
+
+The log level to use, with either the embedded, minimal logger or
+L<Log::Log4perl> if it is installed. Possible values are the same as
+the C<Log::Log4perl> levels: C<TRACE>, C<DEBUG>, C<INFO>, C<WARN>,
+C<ERROR>, and C<FATAL>. The default is C<INFO>.
+
+=item GIT_COMMAND
+
+The path to the C<git> binary to use for the Git features. The default
+is C</usr/local/bin/git>.
+
+=back
+
+=head1 EXIT VALUES
+
+The script exits with zero if it thinks that everything worked, or a
+positive number if it thinks that something failed. Note, however, that
+in some cases it has to divine a failure by the output of things it does
+not control. For now, the exit codes are vague:
+
+	1	An unknown error
+
+	2	The was an external problem
+
+	4	There was an internal problem with the script
+
+	8	A module failed to install
+
+=head1 TO DO
+
+* one shot configuration values from the command line
+
+=head1 BUGS
+
+* none noted
+
+=head1 SEE ALSO
+
+Most behaviour, including environment variables and configuration,
+comes directly from CPAN.pm.
+
+=head1 SOURCE AVAILABILITY
+
+This code is in Github in the CPAN.pm repository:
+
+	https://github.com/andk/cpanpm
+
+The source used to be tracked separately in another GitHub repo,
+but the canonical source is now in the above repo.
+
+=head1 CREDITS
+
+Japheth Cleaver added the bits to allow a forced install (-f).
+
+Jim Brandt suggest and provided the initial implementation for the
+up-to-date and Changes features.
+
+Adam Kennedy pointed out that exit() causes problems on Windows
+where this script ends up with a .bat extension

+=head1 DESCRIPTION
+
+CPAN Mirrors come and go, and maybe you do too. The mirror that was
+fast then might not be fast now, especially if you changed hemispheres.
+
+This program goes through the F<MIRRORED.BY> file and pings a selection
+of mirrors on each continent to find the fastest mirrors. From the best
+continent, it samples several mirrors to find the URL you should add
+to your configuration.
+
+If you don't have a F<MIRRORED.BY> file, this program will download one
+for you. It looks through your existing C<urllist> configuration and
+then default locations. It stores it in C<~/.cpan> (or your configured
+location to store files).
+
+=head1 TO DO
+
+=over 4
+
+=item * Add an option to update the CPAN configuration

+This script provides a command interface (not a shell) to \s-1CPAN.\s0 At the
+moment it uses \s-1CPAN\s0.pm to do the work, but it is not a one-shot command
+runner for \s-1CPAN\s0.pm.
+.SS "Options"
+.IX Subsection "Options"
+.IP "\-a" 4
+.IX Item "-a"
+Creates a \s-1CPAN\s0.pm autobundle with CPAN::Shell\->autobundle.
+.IP "\-A module [ module ... ]" 4
+.IX Item "-A module [ module ... ]"
+Shows the primary maintainers for the specified modules.
+.IP "\-c module" 4
+.IX Item "-c module"
+Runs a `make clean` in the specified module's directories.
+.IP "\-C module [ module ... ]" 4
+.IX Item "-C module [ module ... ]"
+Show the \fIChanges\fR files for the specified modules
+.IP "\-D module [ module ... ]" 4
+.IX Item "-D module [ module ... ]"
+Show the module details. This prints one line for each out-of-date module
+(meaning, modules locally installed but have newer versions on \s-1CPAN\s0).
+Each line has three columns: module name, local version, and \s-1CPAN\s0
+version.
+.IP "\-f" 4
+.IX Item "-f"
+Force the specified action, when it normally would have failed. Use this
+to install a module even if its tests fail. When you use this option,
+\&\-i is not optional for installing a module when you need to force it:
+.Sp
+.Vb 1
+\&        % cpan \-f \-i Module::Foo
+.Ve
+.IP "\-F" 4
+.IX Item "-F"
+Turn off \s-1CPAN\s0.pm's attempts to lock anything. You should be careful with
+this since you might end up with multiple scripts trying to muck in the
+same directory. This isn't so much of a concern if you're loading a special
+config with \f(CW\*(C`\-j\*(C'\fR, and that config sets up its own work directories.

+Download to the current directory the latest distribution of the

+.Sp
+If you want this feature, check out Yanick Champoux's \f(CW\*(C`Git::CPAN::Patch\*(C'\fR

+Print a help message and exit. When you specify \f(CW\*(C`\-h\*(C'\fR, it ignores all
+of the other options and arguments.
+.IP "\-i module [ module ... ]" 4
+.IX Item "-i module [ module ... ]"
+Install the specified modules. With no other switches, this switch
+is implied.
+.IP "\-I" 4

+\&\f(CW\*(C`\-l\*(C'\fR was already taken.
+.IP "\-j Config.pm" 4
+.IX Item "-j Config.pm"
+Load the file that has the \s-1CPAN\s0 configuration data. This should have the
+same format as the standard \fICPAN/Config.pm\fR file, which defines
+\&\f(CW$CPAN::Config\fR as an anonymous hash.
+.Sp
+If the file does not exist, \f(CW\*(C`cpan\*(C'\fR dies.
+.IP "\-J" 4
+.IX Item "-J"
+Dump the configuration in the same format that \s-1CPAN\s0.pm uses. This is useful
+for checking the configuration as well as using the dump as a starting point
+for a new, custom configuration.
+.IP "\-l" 4
+.IX Item "-l"
+List all installed modules with their versions
+.IP "\-L author [ author ... ]" 4
+.IX Item "-L author [ author ... ]"
+List the modules by the specified authors.
+.IP "\-m" 4
+.IX Item "-m"
+Make the specified modules.
+.IP "\-M mirror1,mirror2,..." 4
+.IX Item "-M mirror1,mirror2,..."
+A comma-separated list of mirrors to use for just this run. The \f(CW\*(C`\-P\*(C'\fR
+option can find them for you automatically.
+.IP "\-n" 4
+.IX Item "-n"
+Do a dry run, but don't actually install anything. (unimplemented)
+.IP "\-O" 4
+.IX Item "-O"
+Show the out-of-date modules.
+.IP "\-p" 4
+.IX Item "-p"
+Ping the configured mirrors and print a report
+.IP "\-P" 4
+.IX Item "-P"
+Find the best mirrors you could be using and use them for the current
+session.
+.IP "\-r" 4
+.IX Item "-r"
+Recompiles dynamically loaded modules with CPAN::Shell\->recompile.
+.IP "\-s" 4
+.IX Item "-s"
+Drop in the \s-1CPAN\s0.pm shell. This command does this automatically if you don't
+specify any arguments.
+.IP "\-t module [ module ... ]" 4
+.IX Item "-t module [ module ... ]"
+Run a `make test` on the specified modules.
+.IP "\-T" 4
+.IX Item "-T"
+Do not test modules. Simply install them.
+.IP "\-u" 4
+.IX Item "-u"
+Upgrade all installed modules. Blindly doing this can really break things,
+so keep a backup.
+.IP "\-v" 4
+.IX Item "-v"
+Print the script version and \s-1CPAN\s0.pm version then exit.
+.IP "\-V" 4
+.IX Item "-V"
+Print detailed information about the cpan client.
+.IP "\-w" 4
+.IX Item "-w"
+\&\s-1UNIMPLEMENTED\s0
+.Sp
+Turn on cpan warnings. This checks various things, like directory permissions,
+and tells you about problems you might have.
+.IP "\-x module [ module ... ]" 4
+.IX Item "-x module [ module ... ]"
+Find close matches to the named modules that you think you might have
+mistyped. This requires the optional installation of Text::Levenshtein or

+.IX Header "DESCRIPTION"
+The \s-1CPAN\s0 module automates or at least simplifies the make and install
+of perl modules and extensions. It includes some primitive searching
+capabilities and knows how to use \s-1LWP,\s0 HTTP::Tiny, Net::FTP and certain
+external download clients to fetch distributions from the net.
+.PP
+These are fetched from one or more mirrored \s-1CPAN\s0 (Comprehensive
+Perl Archive Network) sites and unpacked in a dedicated directory.
+.PP
+The \s-1CPAN\s0 module also supports named and versioned
+\&\fIbundles\fR of modules. Bundles simplify handling of sets of
+related modules. See Bundles below.
+.PP
+The package contains a session manager and a cache manager. The
+session manager keeps track of what has been fetched, built, and
+installed in the current session. The cache manager keeps track of the
+disk space occupied by the make processes and deletes excess space
+using a simple \s-1FIFO\s0 mechanism.

+.PP
+eg:

+.PP
+The generated singletons are kept around from instantiation until the
+end of the shell session. <plugin_list> can be reconfigured at any
+time at run time. While the cpan shell is running, it checks all
+activated plugins at each of the 8 reference points listed above and
+runs the respective method if it is implemented for that object. The
+method is called with the active CPAN::Distribution object passed in
+as an argument.
+.SH "CONFIGURATION"
+.IX Header "CONFIGURATION"
+When the \s-1CPAN\s0 module is used for the first time, a configuration
+dialogue tries to determine a couple of site specific options. The
+result of the dialog is stored in a hash reference \f(CW $CPAN::Config \fR
+in a file CPAN/Config.pm.
+.PP
+Default values defined in the CPAN/Config.pm file can be
+overridden in a user specific file: CPAN/MyConfig.pm. Such a file is
+best placed in \f(CW\*(C`$HOME/.cpan/CPAN/MyConfig.pm\*(C'\fR, because \f(CW\*(C`$HOME/.cpan\*(C'\fR is
+added to the search path of the \s-1CPAN\s0 module before the \fBuse()\fR or
+\&\fBrequire()\fR statements. The mkmyconfig command writes this file for you.
+.PP
+The \f(CW\*(C`o conf\*(C'\fR command has various bells and whistles:
+.IP "completion support" 4
+.IX Item "completion support"
+If you have a ReadLine module installed, you can hit \s-1TAB\s0 at any point
+of the commandline and \f(CW\*(C`o conf\*(C'\fR will offer you completion for the
+built-in subcommands and/or config variable names.
+.IP "displaying some help: o conf help" 4
+.IX Item "displaying some help: o conf help"
+Displays a short help
+.IP "displaying current values: o conf [\s-1KEY\s0]" 4
+.IX Item "displaying current values: o conf [KEY]"
+Displays the current value(s) for this config variable. Without \s-1KEY,\s0
+displays all subcommands and config variables.
+.Sp
+Example:
+.Sp
+.Vb 1
+\&  o conf shell
+.Ve
+.Sp
+If \s-1KEY\s0 starts and ends with a slash, the string in between is
+treated as a regular expression and only keys matching this regexp

+.Sp
+.Vb 1
+\&  o conf /color/
+.Ve
+.IP "changing of scalar values: o conf \s-1KEY VALUE\s0" 4

+.IP "changing of list values: o conf \s-1KEY\s0 SHIFT|UNSHIFT|PUSH|POP|SPLICE|LIST" 4
+.IX Item "changing of list values: o conf KEY SHIFT|UNSHIFT|PUSH|POP|SPLICE|LIST"
+If a config variable name ends with \f(CW\*(C`list\*(C'\fR, it is a list. \f(CW\*(C`o conf
+KEY shift\*(C'\fR removes the first element of the list, \f(CW\*(C`o conf KEY pop\*(C'\fR
+removes the last element of the list. \f(CW\*(C`o conf KEYS unshift LIST\*(C'\fR
+prepends a list of values to the list, \f(CW\*(C`o conf KEYS push LIST\*(C'\fR
+appends a list of valued to the list.
+.Sp
+Likewise, \f(CW\*(C`o conf KEY splice LIST\*(C'\fR passes the \s-1LIST\s0 to the corresponding
+splice command.
+.Sp
+Finally, any other list of arguments is taken as a new list value for
+the \s-1KEY\s0 variable discarding the previous value.
+.Sp
+Examples:

+Another peculiarity of urllist is that the site that we could

+If neither your configured \f(CW\*(C`yaml_module\*(C'\fR nor \s-1YAML\s0.pm is installed,

+directory. These files are expected to contain one or more hashrefs.
+For Data::Dumper generated files, this is expected to be done with by
+defining \f(CW$VAR1\fR, \f(CW$VAR2\fR, etc. The \s-1YAML\s0 shell would produce these
+with the command

+For Storable files the rule is that they must be constructed such that
+\&\f(CW\*(C`Storable::retrieve(file)\*(C'\fR returns an array reference and the array
+elements represent one distropref object each. The conversion from
+\&\s-1YAML\s0 would look like so:

+.SS "Cache Manager"
+.IX Subsection "Cache Manager"
+Currently the cache manager only keeps track of the build directory
+($CPAN::Config\->{build_dir}). It is a simple \s-1FIFO\s0 mechanism that
+deletes complete directories below \f(CW\*(C`build_dir\*(C'\fR as soon as the size of
+all directories there gets bigger than \f(CW$CPAN::Config\fR\->{build_cache}
+(in \s-1MB\s0). The contents of this cache may be used for later
+re-installations that you intend to do manually, but will never be
+trusted by \s-1CPAN\s0 itself. This is due to the fact that the user might
+use these directories for building modules on different architectures.
+.PP
+There is another directory ($CPAN::Config\->{keep_source_where}) where
+the original distribution files are kept. This directory is not
+covered by the cache manager and must be controlled by the user. If
+you choose to have the same directory as build_dir and as
+keep_source_where directory, then your sources will be deleted with
+the same fifo mechanism.
+.SS "Bundles"
+.IX Subsection "Bundles"
+A bundle is just a perl module in the namespace Bundle:: that does not
+define any functions or methods. It usually only contains documentation.
+.PP
+It starts like a perl module with a package declaration and a \f(CW$VERSION\fR
+variable. After that the pod section looks like any other pod with the
+only difference being that \fIone special pod section\fR exists starting with
+(verbatim):
+.PP
+.Vb 1
+\&    =head1 CONTENTS
+.Ve
+.PP
+In this pod section each line obeys the format
+.PP
+.Vb 1
+\&        Module_Name [Version_String] [\- optional text]
+.Ve
+.PP
+The only required part is the first field, the name of a module
+(e.g. Foo::Bar, i.e. \fInot\fR the name of the distribution file). The rest
+of the line is optional. The comment part is delimited by a dash just
+as in the man page header.
+.PP
+The distribution of a bundle should follow the same convention as
+other distributions.
+.PP
+Bundles are treated specially in the \s-1CPAN\s0 package. If you say 'install
+Bundle::Tkkit' (assuming such a bundle exists), \s-1CPAN\s0 will install all
+the modules in the \s-1CONTENTS\s0 section of the pod. You can install your
+own Bundles locally by placing a conformant Bundle file somewhere into
+your \f(CW@INC\fR path. The \fBautobundle()\fR command which is available in the
+shell interface does that for you by including all currently installed
+modules in a snapshot bundle file.
+.SH "PREREQUISITES"
+.IX Header "PREREQUISITES"
+The \s-1CPAN\s0 program is trying to depend on as little as possible so the
+user can use it in hostile environment. It works better the more goodies
+the environment provides. For example if you try in the \s-1CPAN\s0 shell
+.PP
+.Vb 1
+\&  install Bundle::CPAN
+.Ve
+.PP
+or
+.PP
+.Vb 1
+\&  install Bundle::CPANxxl
+.Ve
+.PP
+you will find the shell more convenient than the bare shell before.
+.PP
+If you have a local mirror of \s-1CPAN\s0 and can access all files with
+\&\*(L"file:\*(R" URLs, then you only need a perl later than perl5.003 to run
+this module. Otherwise Net::FTP is strongly recommended. \s-1LWP\s0 may be
+required for non-UNIX systems, or if your nearest \s-1CPAN\s0 site is
+associated with a \s-1URL\s0 that is not \f(CW\*(C`ftp:\*(C'\fR.
+.PP
+If you have neither Net::FTP nor \s-1LWP,\s0 there is a fallback mechanism
+implemented for an external ftp command or for an external lynx
+command.
+.SH "UTILITIES"
+.IX Header "UTILITIES"
+.SS "Finding packages and \s-1VERSION\s0"
+.IX Subsection "Finding packages and VERSION"
+This module presumes that all packages on \s-1CPAN\s0
+.IP "\(bu" 2
+declare their \f(CW$VERSION\fR variable in an easy to parse manner. This
+prerequisite can hardly be relaxed because it consumes far too much
+memory to load all packages into the running program just to determine
+the \f(CW$VERSION\fR variable. Currently all programs that are dealing with
+version use something like this

+with little enthusiasm).
+.SS "Debugging"
+.IX Subsection "Debugging"
+Debugging this module is more than a bit complex due to interference from
+the software producing the indices on \s-1CPAN,\s0 the mirroring process on \s-1CPAN,\s0
+packaging, configuration, synchronicity, and even (gasp!) due to bugs
+within the \s-1CPAN\s0.pm module itself.
+.PP
+For debugging the code of \s-1CPAN\s0.pm itself in interactive mode, some
+debugging aid can be turned on for most packages within

+unsigned \s-1MD5\s0 checksums that were used before by \s-1CPAN\s0 protect mainly
+against accidental file corruption.

+You will need to have Module::Signature installed, which in turn

+.SH "POPULATE AN INSTALLATION WITH LOTS OF MODULES"
+.IX Header "POPULATE AN INSTALLATION WITH LOTS OF MODULES"
+Populating a freshly installed perl with one's favorite modules is pretty
+easy if you maintain a private bundle definition file. To get a useful
+blueprint of a bundle definition file, the command autobundle can be used
+on the \s-1CPAN\s0 shell command line. This command writes a bundle definition
+file for all modules installed for the current perl
+interpreter. It's recommended to run this command once only, and from then
+on maintain the file manually under a private name, say
+Bundle/my_bundle.pm. With a clever bundle file you can then simply say
+.PP
+.Vb 1
+\&    cpan> install Bundle::my_bundle
+.Ve
+.PP
+then answer a few questions and go out for coffee (possibly
+even in a different city).
+.PP
+Maintaining a bundle definition file means keeping track of two
+things: dependencies and interactivity. \s-1CPAN\s0.pm sometimes fails on
+calculating dependencies because not all modules define all MakeMaker
+attributes correctly, so a bundle definition file should specify
+prerequisites as early as possible. On the other hand, it's
+annoying that so many distributions need some interactive configuring. So
+what you can try to accomplish in your private bundle file is to have the
+packages that need to be configured early in the file and the gentle
+ones later, so you can go out for coffee after a few minutes and leave \s-1CPAN\s0.pm
+to churn away unattended.

+the interaction between perl, and various firewall configurations. For
+further information on firewalls, it is recommended to consult the
+documentation that comes with the \fIncftp\fR program. If you are unable to
+go through the firewall with a simple Perl setup, it is likely
+that you can configure \fIncftp\fR so that it works through your firewall.
+.SS "Three basic types of firewalls"
+.IX Subsection "Three basic types of firewalls"
+Firewalls can be categorized into three basic types.
+.IP "http firewall" 4
+.IX Item "http firewall"
+This is when the firewall machine runs a web server, and to access the
+outside world, you must do so via that web server. If you set environment
+variables like http_proxy or ftp_proxy to values beginning with http://,
+or in your web browser you've proxy information set, then you know
+you are running behind an http firewall.
+.Sp
+To access servers outside these types of firewalls with perl (even for
+ftp), you need \s-1LWP\s0 or HTTP::Tiny.
+.IP "ftp firewall" 4
+.IX Item "ftp firewall"
+This where the firewall machine runs an ftp server. This kind of
+firewall will only let you access ftp servers outside the firewall.
+This is usually done by connecting to the firewall with ftp, then
+entering a username like \*(L"user@outside.host.com\*(R".
+.Sp
+To access servers outside these type of firewalls with perl, you
+need Net::FTP.
+.IP "One-way visibility" 4
+.IX Item "One-way visibility"
+One-way visibility means these firewalls try to make themselves
+invisible to users inside the firewall. An \s-1FTP\s0 data connection is
+normally created by sending your \s-1IP\s0 address to the remote server and then
+listening for the return connection. But the remote server will not be able to
+connect to you because of the firewall. For these types of firewall,
+\&\s-1FTP\s0 connections need to be done in a passive mode.
+.Sp
+There are two that I can think off.
+.RS 4
+.IP "\s-1SOCKS\s0" 4
+.IX Item "SOCKS"
+If you are using a \s-1SOCKS\s0 firewall, you will need to compile perl and link
+it with the \s-1SOCKS\s0 library.  This is what is normally called a 'socksified'
+perl. With this executable you will be able to connect to servers outside
+the firewall as if it were not there.
+.IP "\s-1IP\s0 Masquerade" 4
+.IX Item "IP Masquerade"
+This is when the firewall implemented in the kernel (via \s-1NAT,\s0 or networking
+address translation), it allows you to hide a complete network behind one
+\&\s-1IP\s0 address. With this firewall no special compiling is needed as you can
+access hosts directly.
+.Sp
+For accessing ftp servers behind such firewalls you usually need to
+set the environment variable \f(CW\*(C`FTP_PASSIVE\*(C'\fR or the config variable
+ftp_passive to a true value.

+I installed a Bundle and had a couple of fails. When I

+.Sp
+The reason for this is that \s-1CPAN\s0 does not know the dependencies of all
+modules when it starts out. To decide about the additional items to
+install, it just uses data found in the \s-1META\s0.yml file or the generated
+Makefile. An undetected missing piece breaks the process. But it may
+well be that your Bundle installs some prerequisite later than some
+depending item and thus your second try is able to resolve everything.

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+CPAN::Admin is a subclass of \s-1CPAN\s0 that adds the commands \f(CW\*(C`register\*(C'\fR
+and \f(CW\*(C`modsearch\*(C'\fR to the \s-1CPAN\s0 shell.
+.PP
+\&\f(CW\*(C`register\*(C'\fR calls \f(CW\*(C`get\*(C'\fR on the named module, assembles a couple of
+informations (description, language), and calls Netscape with the
+\&\-remote argument so that a form is filled with all the assembled
+informations and the registration can be performed with a single
+click. If the command line has more than one argument, register does
+not run a \f(CW\*(C`get\*(C'\fR, instead it interprets the rest of the line as \s-1DSLI\s0
+status, description, and userid and sends them to netscape such that
+the form is again mostly filled and can be edited or confirmed with a
+single click. CPAN::Admin never performs the submission click for you,
+it is only intended to fill in the form on \s-1PAUSE\s0 and leave the
+confirmation to you.
+.PP
+\&\f(CW\*(C`modsearch\*(C'\fR simply passes the arguments to the search engine for the
+modules@perl.org mailing list at <http://www.xray.mpe.mpg.de> where all
+registration requests are stored. It does so in the same way as
+register, namely with the \f(CW\*(C`netscape \-remote\*(C'\fR command.
+.PP
+An experimental feature has also been added, namely to color already
+registered modules in listings. If you have Term::ANSIColor installed,
+the u, r, and m commands will show already registered modules in
+green.
+.SH "PREREQUISITES"
+.IX Header "PREREQUISITES"
+URI::Escape, a browser available in the path, the browser must
+understand the \-remote switch (as far as I know, this is only
+available on \s-1UNIX\s0); coloring of registered modules is only available

+.IP "allow_installing_module_downgrades" 2
+.IX Item "allow_installing_module_downgrades"
+The \s-1CPAN\s0 shell can watch the \f(CW\*(C`blib/\*(C'\fR directories that are built up
+before running \f(CW\*(C`make test\*(C'\fR to determine whether the current
+distribution will end up with modules being overwritten with decreasing module version numbers. It

+downgrade.
+.Sp
+Do you want to allow installing distros with decreasing module
+versions compared to what you have installed (yes, no, ask/yes,
+ask/no)?
+.IP "allow_installing_outdated_dists" 2
+.IX Item "allow_installing_outdated_dists"
+The \s-1CPAN\s0 shell can watch the \f(CW\*(C`blib/\*(C'\fR directories that are built up
+before running \f(CW\*(C`make test\*(C'\fR to determine whether the current
+distribution contains modules that are indexed with a distro with a
+higher distro-version number than the current one. It can
+then let the build of this distro fail when it would not represent the
+most up-to-date version of the distro.
+.Sp
+Note: choosing anything but 'yes' for this option will need
+CPAN::DistnameInfo being installed for taking effect.
+.Sp
+Do you want to allow installing distros that are not indexed as the
+highest distro-version for all contained modules (yes, no, ask/yes,
+ask/no)?
+.IP "auto_commit" 2
+.IX Item "auto_commit"
+Normally \s-1CPAN\s0.pm keeps config variables in memory and changes need to
+be saved in a separate 'o conf commit' command to make them permanent
+between sessions. If you set the 'auto_commit' option to true, changes
+to a config variable are always automatically committed to disk.
+.Sp
+Always commit changes to config variables to disk?
+.IP "build_cache" 2
+.IX Item "build_cache"
+\&\s-1CPAN\s0.pm can limit the size of the disk area for keeping the build
+directories with all the intermediate files.
+.Sp
+Cache size for build directory (in \s-1MB\s0)?
+.IP "build_dir" 2
+.IX Item "build_dir"
+Directory where the build process takes place?
+.IP "build_dir_reuse" 2
+.IX Item "build_dir_reuse"
+Until version 1.88 \s-1CPAN\s0.pm never trusted the contents of the build_dir
+directory between sessions. Since 1.88_58 \s-1CPAN\s0.pm has a YAML-based
+mechanism that makes it possible to share the contents of the
+build_dir/ directory between different sessions with the same version
+of perl. People who prefer to test things several days before
+installing will like this feature because it saves a lot of time.
+.Sp
+If you say yes to the following question, \s-1CPAN\s0 will try to store
+enough information about the build process so that it can pick up in
+future sessions at the same state of affairs as it left a previous
+session.
+.Sp
+Store and re-use state information about distributions between
+\&\s-1CPAN\s0.pm sessions?
+.IP "build_requires_install_policy" 2
+.IX Item "build_requires_install_policy"
+When a module declares another one as a 'build_requires' prerequisite
+this means that the other module is only needed for building or
+testing the module but need not be installed permanently. In this case
+you may wish to install that other module nonetheless or just keep it
+in the 'build_dir' directory to have it available only temporarily.
+Installing saves time on future installations but makes the perl
+installation bigger.
+.Sp
+You can choose if you want to always install (yes), never install (no)
+or be always asked. In the latter case you can set the default answer
+for the question to yes (ask/yes) or no (ask/no).
+.Sp
+Policy on installing 'build_requires' modules (yes, no, ask/yes,
+ask/no)?
+.IP "cache_metadata" 2
+.IX Item "cache_metadata"
+To considerably speed up the initial \s-1CPAN\s0 shell startup, it is
+possible to use Storable to create a cache of metadata. If Storable is
+not available, the normal index mechanism will be used.
+.Sp
+Note: this mechanism is not used when use_sqlite is on and SQLLite is
+running.
+.Sp
+Cache metadata (yes/no)?
+.IP "check_sigs" 2
+.IX Item "check_sigs"
+\&\s-1CPAN\s0 packages can be digitally signed by authors and thus verified
+with the security provided by strong cryptography. The exact mechanism
+is defined in the Module::Signature module. While this is generally
+considered a good thing, it is not always convenient to the end user
+to install modules that are signed incorrectly or where the key of the
+author is not available or where some prerequisite for
+Module::Signature has a bug and so on.
+.Sp
+With the check_sigs parameter you can turn signature checking on and
+off. The default is off for now because the whole tool chain for the
+functionality is not yet considered mature by some. The author of
+\&\s-1CPAN\s0.pm would recommend setting it to true most of the time and
+turning it off only if it turns out to be annoying.
+.Sp
+Note that if you do not have Module::Signature installed, no signature
+checks will be performed at all.
+.Sp
+Always try to check and verify signatures if a \s-1SIGNATURE\s0 file is in
+the package and Module::Signature is installed (yes/no)?
+.IP "cleanup_after_install" 2
+.IX Item "cleanup_after_install"
+Users who install modules and do not intend to look back, can free
+occupied disk space quickly by letting \s-1CPAN\s0.pm cleanup each build
+directory immediately after a successful install.
+.Sp
+Remove build directory after a successful install? (yes/no)?
+.IP "colorize_output" 2
+.IX Item "colorize_output"
+When you have Term::ANSIColor installed, you can turn on colorized
+output to have some visual differences between normal \s-1CPAN\s0.pm output,
+warnings, debugging output, and the output of the modules being
+installed. Set your favorite colors after some experimenting with the
+Term::ANSIColor module.
+.Sp
+Please note that on Windows platforms colorized output also requires
+the Win32::Console::ANSI module.

+.IP "commandnumber_in_prompt" 2
+.IX Item "commandnumber_in_prompt"
+The prompt of the cpan shell can contain the current command number
+for easier tracking of the session or be a plain string.
+.Sp
+Do you want the command number in the prompt (yes/no)?
+.IP "connect_to_internet_ok" 2
+.IX Item "connect_to_internet_ok"
+If you have never defined your own \f(CW\*(C`urllist\*(C'\fR in your configuration
+then \f(CW\*(C`CPAN.pm\*(C'\fR will be hesitant to use the built in default sites for
+downloading. It will ask you once per session if a connection to the
+internet is \s-1OK\s0 and only if you say yes, it will try to connect. But to
+avoid this question, you can choose your favorite download sites once
+and get away with it. Or, if you have no favorite download sites
+answer yes to the following question.
+.Sp
+If no urllist has been chosen yet, would you prefer \s-1CPAN\s0.pm to connect
+to the built-in default sites without asking? (yes/no)?
+.IP "ftp_passive" 2

+Shall we always set the \s-1FTP_PASSIVE\s0 environment variable when dealing
+with ftp download (yes/no)?
+.IP "ftpstats_period" 2

+.Sp
+How many items shall we keep in the statistics about downloads?
+.IP "getcwd" 2
+.IX Item "getcwd"
+\&\s-1CPAN\s0.pm changes the current working directory often and needs to
+determine its own current working directory. Per default it uses
+Cwd::cwd but if this doesn't work on your system for some reason,
+alternatives can be configured according to the following table:
+.Sp

+\&    backtickcwd external command cwd
+.Ve
+.Sp
+Preferred method for determining the current working directory?
+.IP "halt_on_failure" 2
+.IX Item "halt_on_failure"
+Normally, \s-1CPAN\s0.pm continues processing the full list of targets and
+dependencies, even if one of them fails.  However, you can specify
+that \s-1CPAN\s0 should halt after the first failure.  (Note that optional
+recommended or suggested modules that fail will not cause a halt.)
+.Sp
+Do you want to halt on failure (yes/no)?
+.IP "histfile" 2
+.IX Item "histfile"
+If you have one of the readline packages (Term::ReadLine::Perl,
+Term::ReadLine::Gnu, possibly others) installed, the interactive \s-1CPAN\s0
+shell will have history support. The next two questions deal with the
+filename of the history file and with its size. If you do not want to
+set this variable, please hit \s-1SPACE ENTER\s0 to the following question.
+.Sp
+File to save your history?
+.IP "histsize" 2
+.IX Item "histsize"
+Number of lines to save?
+.IP "inactivity_timeout" 2
+.IX Item "inactivity_timeout"
+Sometimes you may wish to leave the processes run by \s-1CPAN\s0 alone
+without caring about them. Because the Makefile.PL or the Build.PL
+sometimes contains question you're expected to answer, you can set a
+timer that will kill a 'perl Makefile.PL' process after the specified
+time in seconds.
+.Sp
+If you set this value to 0, these processes will wait forever. This is
+the default and recommended setting.
+.Sp
+Timeout for inactivity during {Makefile,Build}.PL?
+.IP "index_expire" 2
+.IX Item "index_expire"
+The \s-1CPAN\s0 indexes are usually rebuilt once or twice per hour, but the
+typical \s-1CPAN\s0 mirror mirrors only once or twice per day. Depending on
+the quality of your mirror and your desire to be on the bleeding edge,
+you may want to set the following value to more or less than one day
+(which is the default). It determines after how many days \s-1CPAN\s0.pm
+downloads new indexes.
+.Sp
+Let the index expire after how many days?
+.IP "inhibit_startup_message" 2
+.IX Item "inhibit_startup_message"
+When the \s-1CPAN\s0 shell is started it normally displays a greeting message
+that contains the running version and the status of readline support.
+.Sp
+Do you want to turn this message off?
+.IP "keep_source_where" 2
+.IX Item "keep_source_where"
+Unless you are accessing the \s-1CPAN\s0 on your filesystem via a file: \s-1URL,
+CPAN\s0.pm needs to keep the source files it downloads somewhere. Please
+supply a directory where the downloaded files are to be kept.
+.Sp
+Download target directory?
+.IP "load_module_verbosity" 2
+.IX Item "load_module_verbosity"
+When \s-1CPAN\s0.pm loads a module it needs for some optional feature, it
+usually reports about module name and version. Choose 'v' to get this
+message, 'none' to suppress it.
+.Sp
+Verbosity level for loading modules (none or v)?
+.IP "makepl_arg" 2
+.IX Item "makepl_arg"
+Every Makefile.PL is run by perl in a separate process. Likewise we
+run 'make' and 'make install' in separate processes. If you have
+any parameters (e.g. \s-1PREFIX, UNINST\s0 or the like) you want to
+pass to the calls, please specify them here.

+.IP "prefer_installer" 2
+.IX Item "prefer_installer"
+When you have Module::Build installed and a module comes with both a
+Makefile.PL and a Build.PL, which shall have precedence?
+.Sp
+The main two standard installer modules are the old and well
+established ExtUtils::MakeMaker (for short: \s-1EUMM\s0) which uses the
+Makefile.PL. And the next generation installer Module::Build (\s-1MB\s0)
+which works with the Build.PL (and often comes with a Makefile.PL
+too). If a module comes only with one of the two we will use that one
+but if both are supplied then a decision must be made between \s-1EUMM\s0 and
+\&\s-1MB.\s0 See also http://rt.cpan.org/Ticket/Display.html?id=29235 for a
+discussion about the right default.
+.Sp
+Or, as a third option you can choose \s-1RAND\s0 which will make a random
+decision (something regular \s-1CPAN\s0 testers will enjoy).
+.Sp
+In case you can choose between running a Makefile.PL or a Build.PL,
+which installer would you prefer (\s-1EUMM\s0 or \s-1MB\s0 or \s-1RAND\s0)?
+.IP "prefs_dir" 2
+.IX Item "prefs_dir"
+\&\s-1CPAN\s0.pm can store customized build environments based on regular
+expressions for distribution names. These are \s-1YAML\s0 files where the
+default options for \s-1CPAN\s0.pm and the environment can be overridden and
+dialog sequences can be stored that can later be executed by an
+Expect.pm object. The \s-1CPAN\s0.pm distribution comes with some prefab \s-1YAML\s0
+files that cover sample distributions that can be used as blueprints
+to store your own prefs. Please check out the distroprefs/ directory of
+the \s-1CPAN\s0.pm distribution to get a quick start into the prefs system.
+.Sp
+Directory where to store default options/environment/dialogs for
+building modules that need some customization?
+.IP "prerequisites_policy" 2
+.IX Item "prerequisites_policy"
+The \s-1CPAN\s0 module can detect when a module which you are trying to build
+depends on prerequisites. If this happens, it can build the
+prerequisites for you automatically ('follow'), ask you for
+confirmation ('ask'), or just ignore them ('ignore').  Choosing
+\&'follow' also sets \s-1PERL_AUTOINSTALL\s0 and \s-1PERL_EXTUTILS_AUTOINSTALL\s0 for
+\&\*(L"\-\-defaultdeps\*(R" if not already set.
+.Sp
+Please set your policy to one of the three values.
+.Sp
+Policy on building prerequisites (follow, ask or ignore)?
+.IP "randomize_urllist" 2
+.IX Item "randomize_urllist"
+\&\s-1CPAN\s0.pm can introduce some randomness when using hosts for download
+that are configured in the urllist parameter. Enter a numeric value
+between 0 and 1 to indicate how often you want to let \s-1CPAN\s0.pm try a
+random host from the urllist. A value of one specifies to always use a
+random host as the first try. A value of zero means no randomness at
+all. Anything in between specifies how often, on average, a random
+host should be tried first.
+.Sp
+Randomize parameter
+.IP "recommends_policy" 2
+.IX Item "recommends_policy"
+(Experimental feature!) Some \s-1CPAN\s0 modules recommend additional, optional dependencies.  These should
+generally be installed except in resource constrained environments.  When this
+policy is true, recommended modules will be included with required modules.
+.Sp
+Include recommended modules?
+.IP "scan_cache" 2
+.IX Item "scan_cache"
+By default, each time the \s-1CPAN\s0 module is started, cache scanning is
+performed to keep the cache size in sync ('atstart'). Alternatively,
+scanning and cleanup can happen when \s-1CPAN\s0 exits ('atexit'). To prevent
+any cache cleanup, answer 'never'.
+.Sp
+Perform cache scanning ('atstart', 'atexit' or 'never')?
+.IP "shell" 2
+.IX Item "shell"
+What is your favorite shell?
+.IP "show_unparsable_versions" 2
+.IX Item "show_unparsable_versions"
+During the 'r' command \s-1CPAN\s0.pm finds modules without version number.
+When the command finishes, it prints a report about this. If you
+want this report to be very verbose, say yes to the following
+variable.
+.Sp
+Show all individual modules that have no \f(CW$VERSION\fR?
+.IP "show_upload_date" 2
+.IX Item "show_upload_date"
+The 'd' and the 'm' command normally only show you information they
+have in their in-memory database and thus will never connect to the
+internet. If you set the 'show_upload_date' variable to true, 'm' and
+\&'d' will additionally show you the upload date of the module or
+distribution. Per default this feature is off because it may require a
+net connection to get at the upload date.
+.Sp
+Always try to show upload date with 'd' and 'm' command (yes/no)?
+.IP "show_zero_versions" 2
+.IX Item "show_zero_versions"
+During the 'r' command \s-1CPAN\s0.pm finds modules with a version number of
+zero. When the command finishes, it prints a report about this. If you
+want this report to be very verbose, say yes to the following
+variable.
+.Sp
+Show all individual modules that have a \f(CW$VERSION\fR of zero?
+.IP "suggests_policy" 2
+.IX Item "suggests_policy"
+(Experimental feature!) Some \s-1CPAN\s0 modules suggest additional, optional dependencies.  These 'suggest'

+.Sp
+Include suggested modules?
+.IP "tar_verbosity" 2
+.IX Item "tar_verbosity"
+When \s-1CPAN\s0.pm uses the tar command, which switch for the verbosity
+shall be used? Choose 'none' for quiet operation, 'v' for file
+name listing, 'vv' for full listing.
+.Sp
+Tar command verbosity level (none or v or vv)?
+.IP "term_is_latin" 2
+.IX Item "term_is_latin"
+The next option deals with the charset (a.k.a. character set) your
+terminal supports. In general, \s-1CPAN\s0 is English speaking territory, so
+the charset does not matter much but some \s-1CPAN\s0 have names that are
+outside the \s-1ASCII\s0 range. If your terminal supports \s-1UTF\-8,\s0 you should
+say no to the next question. If it expects \s-1ISO\-8859\-1\s0 (also known as
+\&\s-1LATIN1\s0) then you should say yes. If it supports neither, your answer
+does not matter because you will not be able to read the names of some
+authors anyway. If you answer no, names will be output in \s-1UTF\-8.\s0
+.Sp
+Your terminal expects \s-1ISO\-8859\-1\s0 (yes/no)?

+Do you want to turn ornaments on?
+.IP "test_report" 2
+.IX Item "test_report"
+The goal of the \s-1CPAN\s0 Testers project (http://testers.cpan.org/) is to
+test as many \s-1CPAN\s0 packages as possible on as many platforms as
+possible.  This provides valuable feedback to module authors and
+potential users to identify bugs or platform compatibility issues and
+improves the overall quality and value of \s-1CPAN.\s0
+.Sp
+One way you can contribute is to send test results for each module
+that you install.  If you install the CPAN::Reporter module, you have
+the option to automatically generate and deliver test reports to \s-1CPAN\s0
+Testers whenever you run tests on a \s-1CPAN\s0 package.

+.IP "prefer_external_tar" 2
+.IX Item "prefer_external_tar"
+Per default all untar operations are done with the perl module

+.IP "trust_test_report_history" 2
+.IX Item "trust_test_report_history"
+When a distribution has already been tested by CPAN::Reporter on
+this machine, \s-1CPAN\s0 can skip the test phase and just rely on the
+test report history instead.
+.Sp
+Note that this will not apply to distributions that failed tests
+because of missing dependencies.  Also, tests can be run
+regardless of the history using \*(L"force\*(R".
+.Sp
+Do you want to rely on the test report history (yes/no)?
+.IP "urllist_ping_external" 2
+.IX Item "urllist_ping_external"
+When automatic selection of the nearest cpan mirrors is performed,
+turn on the use of the external ping via Net::Ping::External. This is
+recommended in the case the local network has a transparent proxy.
+.Sp
+Do you want to use the external ping command when autoselecting
+mirrors?
+.IP "urllist_ping_verbose" 2
+.IX Item "urllist_ping_verbose"
+When automatic selection of the nearest cpan mirrors is performed,
+this option can be used to turn on verbosity during the selection
+process.
+.Sp
+Do you want to see verbosity turned on when autoselecting mirrors?
+.IP "use_prompt_default" 2
+.IX Item "use_prompt_default"
+When this is true, \s-1CPAN\s0 will set \s-1PERL_MM_USE_DEFAULT\s0 to a true
+value.  This causes ExtUtils::MakeMaker (and compatible) prompts
+to use default values instead of stopping to prompt you to answer
+questions. It also sets \s-1NONINTERACTIVE_TESTING\s0 to a true value to
+signal more generally that distributions should not try to
+interact with you.
+.Sp
+Do you want to use prompt defaults (yes/no)?
+.IP "use_sqlite" 2
+.IX Item "use_sqlite"
+CPAN::SQLite is a layer between the index files that are downloaded
+from the \s-1CPAN\s0 and \s-1CPAN\s0.pm that speeds up metadata queries and reduces
+memory consumption of \s-1CPAN\s0.pm considerably.
+.Sp
+Use CPAN::SQLite if available? (yes/no)?
+.IP "version_timeout" 2
+.IX Item "version_timeout"
+This timeout prevents \s-1CPAN\s0 from hanging when trying to parse a
+pathologically coded \f(CW$VERSION\fR from a module.
+.Sp
+The default is 15 seconds.  If you set this value to 0, no timeout
+will occur, but this is not recommended.
+.Sp
+Timeout for parsing module versions?
+.IP "yaml_load_code" 2
+.IX Item "yaml_load_code"
+Both \s-1YAML\s0.pm and YAML::Syck are capable of deserialising code. As this
+requires a string eval, which might be a security risk, you can use
+this option to enable or disable the deserialisation of code via
+CPAN::DeferredCode. (Note: This does not work under perl 5.6)
+.Sp
+Do you want to enable code deserialisation (yes/no)?
+.IP "yaml_module" 2
+.IX Item "yaml_module"
+At the time of this writing (2009\-03) there are three \s-1YAML\s0
+implementations working: \s-1YAML,\s0 YAML::Syck, and \s-1YAML::XS.\s0 The latter
+two are faster but need a C compiler installed on your system. There
+may be more alternative \s-1YAML\s0 conforming modules. When I tried two
+other players, YAML::Tiny and YAML::Perl, they seemed not powerful
+enough to work with \s-1CPAN\s0.pm. This may have changed in the meantime.
+.Sp
+Which \s-1YAML\s0 implementation would you prefer?

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+This module can serve as a transparent interface to any \s-1TIEHASH\s0 package
+that is required to store arbitrary perl data, including nested references.
+Thus, this module can be used for storing references and other arbitrary data
+within \s-1DBM\s0 databases.
+.PP
+It works by serializing the references in the hash into a single string. In the
+underlying \s-1TIEHASH\s0 package (usually a \s-1DBM\s0 database), it is this string that
+gets stored.  When the value is fetched again, the string is deserialized to
+reconstruct the data structure into memory.
+.PP
+For historical and practical reasons, it requires the \fBData::Dumper\fR package,
+available at any \s-1CPAN\s0 site. \fBData::Dumper\fR gives you really nice-looking dumps of
+your data structures, in case you wish to look at them on the screen, and
+it was the only serializing engine before version 2.00.  However, as of version
+2.00, you can use any of \fBData::Dumper\fR, \fBFreezeThaw\fR or \fBStorable\fR to
+perform the underlying serialization, as hinted at by the \s-1SYNOPSIS\s0 overview
+above.  Using \fBStorable\fR is usually much faster than the other methods.
+.PP
+See the \s-1BUGS\s0 section for important limitations.
+.SS "Changing the Defaults"
+.IX Subsection "Changing the Defaults"
+\&\fB\s-1MLDBM\s0\fR relies on an underlying \s-1TIEHASH\s0 implementation (usually a
+\&\s-1DBM\s0 package), and an underlying serialization package.  The respective
+defaults are \fBSDBM_File\fR and \fBData::Dumper\fR.  Both of these defaults
+can be changed.  Changing the \fBSDBM_File\fR default is strongly recommended.
+See \s-1WARNINGS\s0 below.
+.PP
+Three serialization wrappers are currently supported: \fBData::Dumper\fR,
+\&\fBStorable\fR, and \fBFreezeThaw\fR.  Additional serializers can be
+supported by writing a wrapper that implements the interface required by
+\&\fBMLDBM::Serializer\fR.  See the supported wrappers and the \fBMLDBM::Serializer\fR
+source for details.
+.PP
+In the following, \fI\f(CI$OBJ\fI\fR stands for the tied object, as in:
+.PP
+.Vb 2

+.IX Item "$MLDBM::UseDB or $OBJ->UseDB([TIEDOBJECT])"
+The global \f(CW$MLDBM::UseDB\fR can be set to default to something other than
+\&\f(CW\*(C`SDBM_File\*(C'\fR, in case you have a more efficient \s-1DBM,\s0 or if you want to use
+this with some other \s-1TIEHASH\s0 implementation.  Alternatively, you can specify
+the name of the package at \f(CW\*(C`use\*(C'\fR time, as the first \*(L"parameter\*(R".
+Nested module names can be specified as \*(L"Foo::Bar\*(R".
+.Sp
+The corresponding method call returns the underlying \s-1TIEHASH\s0 object when
+called without arguments.  It can be called with any object that
+implements Perl's \s-1TIEHASH\s0 interface, to set that value.

+.SS "Controlling Serializer Properties"
+.IX Subsection "Controlling Serializer Properties"
+These methods are meant to supply an interface to the properties of the
+underlying serializer used.  Do \fBnot\fR call or set them without
+understanding the consequences in full.  The defaults are usually sensible.
+.PP
+Not all of these necessarily apply to all the supplied serializers, so we
+specify when to apply them.  Failure to respect this will usually lead to
+an exception.

+If the serializer provides alternative serialization methods, this
+can be used to set them.
+.Sp
+With \fBData::Dumper\fR (which offers a pure Perl and an \s-1XS\s0 verion
+of its serializing routine), this is set to \f(CW\*(C`Dumpxs\*(C'\fR by default if that
+is supported in your installation.  Otherwise, defaults to the slower
+\&\f(CW\*(C`Dump\*(C'\fR method.
+.Sp
+With \fBStorable\fR, a value of \f(CW\*(C`portable\*(C'\fR requests that serialization be
+architecture neutral, i.e. the deserialization can later occur on another
+platform. Of course, this only makes sense if your database files are
+themselves architecture neutral.  By default, native format is used for
+greater serializing speed in \fBStorable\fR.  Both \fBData::Dumper\fR and
+\&\fBFreezeThaw\fR are always architecture neutral.

+.IX Item "$MLDBM::Key or $OBJ->Key([KEYSTRING])"
+If the serializer only deals with part of the data (perhaps because
+the \s-1TIEHASH\s0 object can natively store some types of data), it may need
+a unique key string to recognize the data it handles.  This can be used
+to set that string.  Best left alone.
+.Sp
+Defaults to the magic string used to recognize \s-1MLDBM\s0 data. It is a six
+character wide, unique string. This is best left alone, unless you know

+.IX Item "$MLDBM::RemoveTaint or $OBJ->RemoveTaint([BOOL])"
+If the serializer can optionally untaint any retrieved data subject to
+taint checks in Perl, this can be used to request that feature.  Data
+that comes from external sources (like disk-files) must always be
+viewed with caution, so use this only when you are sure that that is
+not an issue.
+.Sp
+\&\fBData::Dumper\fR uses \f(CW\*(C`eval()\*(C'\fR to deserialize and is therefore subject to
+taint checks.  Can be set to a true value to make the \fBData::Dumper\fR
+serializer untaint the data retrieved. It is not enabled by default.

+.Ve
+.SH "BUGS"
+.IX Header "BUGS"
+.IP "1." 4
+Adding or altering substructures to a hash value is not entirely transparent
+in current perl.  If you want to store a reference or modify an existing
+reference value in the \s-1DBM,\s0 it must first be retrieved and stored in a
+temporary variable for further modifications.  In particular, something like
+this will \s-1NOT\s0 work properly:
+.Sp
+.Vb 1
+\&        $mldb{key}{subkey}[3] = \*(Aqstuff\*(Aq;        # won\*(Aqt work
+.Ve
+.Sp
+Instead, that must be written as:
+.Sp
+.Vb 3
+\&        $tmp = $mldb{key};                      # retrieve value
+\&        $tmp\->{subkey}[3] = \*(Aqstuff\*(Aq;
+\&        $mldb{key} = $tmp;                      # store value
+.Ve
+.Sp
+This limitation exists because the perl \s-1TIEHASH\s0 interface currently has no
+support for multidimensional ties.
+.IP "2." 4
+The \fBData::Dumper\fR serializer uses \fBeval()\fR.  A lot.  Try the \fBStorable\fR
+serializer, which is generally the most efficient.
+.SH "WARNINGS"
+.IX Header "WARNINGS"
+.IP "1." 4
+Many \s-1DBM\s0 implementations have arbitrary limits on the size of records
+that can be stored.  For example, \s-1SDBM\s0 and many \s-1ODBM\s0 or \s-1NDBM\s0
+implementations have a default limit of 1024 bytes for the size of a
+record.  \s-1MLDBM\s0 can easily exceed these limits when storing large data
+structures, leading to mysterious failures.  Although SDBM_File is
+used by \s-1MLDBM\s0 by default, it is not a good choice if you're storing
+large data structures.  Berkeley \s-1DB\s0 and \s-1GDBM\s0 both do not have these
+limits, so I recommend using either of those instead.
+.IP "2." 4
+\&\s-1MLDBM\s0 does well with data structures that are not too deep and not
+too wide.  You also need to be careful about how many \f(CW\*(C`FETCH\*(C'\fRes your
+code actually ends up doing.  Meaning, you should get the most mileage
+out of a \f(CW\*(C`FETCH\*(C'\fR by holding on to the highest level value for as long
+as you need it.  Remember that every toplevel access of the tied hash,
+for example \f(CW$mldb{foo}\fR, translates to a \s-1MLDBM\s0 \f(CW\*(C`FETCH()\*(C'\fR call.
+.Sp
+Too often, people end up writing something like this:
+.Sp
+.Vb 4
+\&        tie %h, \*(AqMLDBM\*(Aq, ...;
+\&        for my $k (keys %{$h{something}}) {
+\&            print $h{something}{$k}[0]{foo}{bar};  # FETCH _every_ time!
+\&        }
+.Ve
+.Sp
+when it should be written this for efficiency:
+.Sp
+.Vb 5
+\&        tie %h, \*(AqMLDBM\*(Aq, ...;
+\&        my $root = $h{something};                  # FETCH _once_

+
+=item -C module [ module ... ]
+
+Show the F<Changes> files for the specified modules
+
+=item -D module [ module ... ]
+
+Show the module details. This prints one line for each out-of-date module
+(meaning, modules locally installed but have newer versions on CPAN).
+Each line has three columns: module name, local version, and CPAN
+version.
+
+=item -f
+
+Force the specified action, when it normally would have failed. Use this
+to install a module even if its tests fail. When you use this option,
+-i is not optional for installing a module when you need to force it:
+
+	% cpan -f -i Module::Foo
+
+=item -F
+
+Turn off CPAN.pm's attempts to lock anything. You should be careful with
+this since you might end up with multiple scripts trying to muck in the
+same directory. This isn't so much of a concern if you're loading a special
+config with C<-j>, and that config sets up its own work directories.
+
+=item -g module [ module ... ]
+
+Downloads to the current directory the latest distribution of the module.
+
+=item -G module [ module ... ]
+
+UNIMPLEMENTED
+
+Download to the current directory the latest distribution of the
+modules, unpack each distribution, and create a git repository for each
+distribution.
+
+If you want this feature, check out Yanick Champoux's C<Git::CPAN::Patch>
+distribution.
+
+=item -h
+
+Print a help message and exit. When you specify C<-h>, it ignores all
+of the other options and arguments.
+
+=item -i module [ module ... ]
+
+Install the specified modules. With no other switches, this switch
+is implied.
+
+=item -I
+
+Load C<local::lib> (think like C<-I> for loading lib paths). Too bad
+C<-l> was already taken.
+
+=item -j Config.pm
+
+Load the file that has the CPAN configuration data. This should have the
+same format as the standard F<CPAN/Config.pm> file, which defines
+C<$CPAN::Config> as an anonymous hash.
+
+If the file does not exist, C<cpan> dies.
+
+=item -J
+
+Dump the configuration in the same format that CPAN.pm uses. This is useful
+for checking the configuration as well as using the dump as a starting point
+for a new, custom configuration.
+
+=item -l
+
+List all installed modules with their versions
+
+=item -L author [ author ... ]
+
+List the modules by the specified authors.
+
+=item -m
+
+Make the specified modules.
+
+=item -M mirror1,mirror2,...
+
+A comma-separated list of mirrors to use for just this run. The C<-P>
+option can find them for you automatically.
+
+=item -n
+
+Do a dry run, but don't actually install anything. (unimplemented)
+
+=item -O
+
+Show the out-of-date modules.
+
+=item -p
+
+Ping the configured mirrors and print a report
+
+=item -P
+
+Find the best mirrors you could be using and use them for the current
+session.
+
+=item -r
+
+Recompiles dynamically loaded modules with CPAN::Shell->recompile.
+
+=item -s
+
+Drop in the CPAN.pm shell. This command does this automatically if you don't
+specify any arguments.
+
+=item -t module [ module ... ]
+
+Run a `make test` on the specified modules.
+
+=item -T
+
+Do not test modules. Simply install them.
+
+=item -u
+
+Upgrade all installed modules. Blindly doing this can really break things,
+so keep a backup.
+
+=item -v
+
+Print the script version and CPAN.pm version then exit.
+
+=item -V
+
+Print detailed information about the cpan client.
+
+=item -w
+
+UNIMPLEMENTED
+
+Turn on cpan warnings. This checks various things, like directory permissions,
+and tells you about problems you might have.
+
+=item -x module [ module ... ]
+
+Find close matches to the named modules that you think you might have
+mistyped. This requires the optional installation of Text::Levenshtein or
+Text::Levenshtein::Damerau.
+
+=item -X
+
+Dump all the namespaces to standard output.

+=head2 Environment variables
+
+There are several components in CPAN.pm that use environment variables.
+The build tools, L<ExtUtils::MakeMaker> and L<Module::Build> use some,
+while others matter to the levels above them. Some of these are specified
+by the Perl Toolchain Gang:
+
+Lancaster Concensus: L<https://github.com/Perl-Toolchain-Gang/toolchain-site/blob/master/lancaster-consensus.md>

+=head1 EXIT VALUES
+
+The script exits with zero if it thinks that everything worked, or a
+positive number if it thinks that something failed. Note, however, that
+in some cases it has to divine a failure by the output of things it does
+not control. For now, the exit codes are vague:
+
+	1	An unknown error
+
+	2	The was an external problem
+
+	4	There was an internal problem with the script
+
+	8	A module failed to install
+
+=head1 TO DO
+
+* There is initial support for Log4perl if it is available, but I
+haven't gone through everything to make the NullLogger work out
+correctly if Log4perl is not installed.
+
+* When I capture CPAN.pm output, I need to check for errors and
+report them to the user.
+
+* Warnings switch
+
+* Check then exit
+
+=head1 BUGS
+
+* none noted

+=head1 SOURCE AVAILABILITY
+
+This code is in Github in the CPAN.pm repository:
+
+	https://github.com/andk/cpanpm
+
+The source used to be tracked separately in another GitHub repo,
+but the canonical source is now in the above repo.
+
+=head1 CREDITS
+
+Japheth Cleaver added the bits to allow a forced install (C<-f>).
+
+Jim Brandt suggest and provided the initial implementation for the
+up-to-date and Changes features.
+
+Adam Kennedy pointed out that C<exit()> causes problems on Windows
+where this script ends up with a .bat extension
+
+David Golden helps integrate this into the C<CPAN.pm> repos.
+
+Jim Keenan fixed up various issues with _download

+#       The original intent of __DIE__ was only to allow you to substitute one
+#       kind of death for another on an application-wide basis without respect
+#       to whether you were in an eval or not.  As a global backstop, it should
+#       not be used any more lightly (or any more heavily :-) than class
+#       UNIVERSAL.  Any attempt to build a general exception model on it should
+#       be politely squashed.  Any bug that causes every eval {} to have to be
+#       modified should be not so politely squashed.
+#
+#       Those are my current opinions.  It is also my opinion that polite
+#       arguments degenerate to personal arguments far too frequently, and that
+#       when they do, it's because both people wanted it to, or at least didn't
+#       sufficiently want it not to.

+=head1 DESCRIPTION
+
+The CPAN module automates or at least simplifies the make and install
+of perl modules and extensions. It includes some primitive searching
+capabilities and knows how to use LWP, HTTP::Tiny, Net::FTP and certain
+external download clients to fetch distributions from the net.
+
+These are fetched from one or more mirrored CPAN (Comprehensive
+Perl Archive Network) sites and unpacked in a dedicated directory.
+
+The CPAN module also supports named and versioned
+I<bundles> of modules. Bundles simplify handling of sets of
+related modules. See Bundles below.
+
+The package contains a session manager and a cache manager. The
+session manager keeps track of what has been fetched, built, and
+installed in the current session. The cache manager keeps track of the
+disk space occupied by the make processes and deletes excess space
+using a simple FIFO mechanism.
+
+All methods provided are accessible in a programmer style and in an
+interactive shell style.
+
+=head2 CPAN::shell([$prompt, $command]) Starting Interactive Mode
+
+Enter interactive mode by running
+
+    perl -MCPAN -e shell
+
+or
+
+    cpan
+
+which puts you into a readline interface. If C<Term::ReadKey> and
+either of C<Term::ReadLine::Perl> or C<Term::ReadLine::Gnu> are installed,
+history and command completion are supported.
+
+Once at the command line, type C<h> for one-page help
+screen; the rest should be self-explanatory.
+
+The function call C<shell> takes two optional arguments: one the
+prompt, the second the default initial command line (the latter
+only works if a real ReadLine interface module is installed).
+
+The most common uses of the interactive modes are
+
+=over 2
+
+=item Searching for authors, bundles, distribution files and modules
+
+There are corresponding one-letter commands C<a>, C<b>, C<d>, and C<m>
+for each of the four categories and another, C<i> for any of the
+mentioned four. Each of the four entities is implemented as a class
+with slightly differing methods for displaying an object.
+
+Arguments to these commands are either strings exactly matching
+the identification string of an object, or regular expressions
+matched case-insensitively against various attributes of the
+objects. The parser only recognizes a regular expression when you
+enclose it with slashes.
+
+The principle is that the number of objects found influences how an
+item is displayed. If the search finds one item, the result is
+displayed with the rather verbose method C<as_string>, but if
+more than one is found, each object is displayed with the terse method
+C<as_glimpse>.
+
+Examples:

+  Module    Text::Lorem            (ADEOLA/Text-Lorem-0.3.tar.gz)
+  Module    Text::Lorem::More      (RKRIMEN/Text-Lorem-More-0.12.tar.gz)

+  Module  = DateTime::TimeZone::Europe::Berlin (DROLSKY/DateTime-TimeZone-0.7904.tar.gz)
+  Module    Filter::NumberLines    (BEATNIK/Filter-NumberLines-0.02.tar.gz)
+  Author          [...]
+
+The examples illustrate several aspects: the first three queries
+target modules, authors, or distros directly and yield exactly one
+result. The last two use regular expressions and yield several
+results. The last one targets all of bundles, modules, authors, and
+distros simultaneously. When more than one result is available, they
+are printed in one-line format.
+
+=item C<get>, C<make>, C<test>, C<install>, C<clean> modules or distributions
+
+These commands take any number of arguments and investigate what is
+necessary to perform the action. Argument processing is as follows:
+
+  known module name in format Foo/Bar.pm   module
+  other embedded slash                     distribution
+    - with trailing slash dot              directory
+  enclosing slashes                        regexp
+  known module name in format Foo::Bar     module
+
+If the argument is a distribution file name (recognized by embedded
+slashes), it is processed. If it is a module, CPAN determines the
+distribution file in which this module is included and processes that,
+following any dependencies named in the module's META.yml or
+Makefile.PL (this behavior is controlled by the configuration
+parameter C<prerequisites_policy>). If an argument is enclosed in
+slashes it is treated as a regular expression: it is expanded and if
+the result is a single object (distribution, bundle or module), this
+object is processed.
+
+Example:
+
+    install Dummy::Perl                   # installs the module
+    install AUXXX/Dummy-Perl-3.14.tar.gz  # installs that distribution
+    install /Dummy-Perl-3.14/             # same if the regexp is unambiguous
+
+C<get> downloads a distribution file and untars or unzips it, C<make>
+builds it, C<test> runs the test suite, and C<install> installs it.
+
+Any C<make> or C<test> is run unconditionally. An
+
+  install <distribution_file>
+
+is also run unconditionally. But for
+
+  install <module>
+
+CPAN checks whether an install is needed and prints
+I<module up to date> if the distribution file containing
+the module doesn't need updating.
+
+CPAN also keeps track of what it has done within the current session
+and doesn't try to build a package a second time regardless of whether it
+succeeded or not. It does not repeat a test run if the test
+has been run successfully before. Same for install runs.
+
+The C<force> pragma may precede another command (currently: C<get>,
+C<make>, C<test>, or C<install>) to execute the command from scratch
+and attempt to continue past certain errors. See the section below on
+the C<force> and the C<fforce> pragma.
+
+The C<notest> pragma skips the test part in the build
+process.
+
+Example:
+
+    cpan> notest install Tk
+
+A C<clean> command results in a
+
+  make clean
+
+being executed within the distribution file's working directory.
+
+=item C<readme>, C<perldoc>, C<look> module or distribution
+
+C<readme> displays the README file of the associated distribution.
+C<Look> gets and untars (if not yet done) the distribution file,
+changes to the appropriate directory and opens a subshell process in
+that directory. C<perldoc> displays the module's pod documentation
+in html or plain text format.
+
+=item C<ls> author
+
+=item C<ls> globbing_expression
+
+The first form lists all distribution files in and below an author's
+CPAN directory as stored in the CHECKSUMS files distributed on
+CPAN. The listing recurses into subdirectories.
+
+The second form limits or expands the output with shell
+globbing as in the following examples:
+
+      ls JV/make*
+      ls GSAR/*make*
+      ls */*make*
+
+The last example is very slow and outputs extra progress indicators
+that break the alignment of the result.
+
+Note that globbing only lists directories explicitly asked for, for
+example FOO/* will not list FOO/bar/Acme-Sthg-n.nn.tar.gz. This may be
+regarded as a bug that may be changed in some future version.
+
+=item C<failed>
+
+The C<failed> command reports all distributions that failed on one of
+C<make>, C<test> or C<install> for some reason in the currently
+running shell session.
+
+=item Persistence between sessions
+
+If the C<YAML> or the C<YAML::Syck> module is installed a record of
+the internal state of all modules is written to disk after each step.
+The files contain a signature of the currently running perl version
+for later perusal.
+
+If the configurations variable C<build_dir_reuse> is set to a true
+value, then CPAN.pm reads the collected YAML files. If the stored
+signature matches the currently running perl, the stored state is
+loaded into memory such that persistence between sessions
+is effectively established.
+
+=item The C<force> and the C<fforce> pragma
+
+To speed things up in complex installation scenarios, CPAN.pm keeps
+track of what it has already done and refuses to do some things a
+second time. A C<get>, a C<make>, and an C<install> are not repeated.
+A C<test> is repeated only if the previous test was unsuccessful. The
+diagnostic message when CPAN.pm refuses to do something a second time
+is one of I<Has already been >C<unwrapped|made|tested successfully> or
+something similar. Another situation where CPAN refuses to act is an
+C<install> if the corresponding C<test> was not successful.
+
+In all these cases, the user can override this stubborn behaviour by
+prepending the command with the word force, for example:
+
+  cpan> force get Foo
+  cpan> force make AUTHOR/Bar-3.14.tar.gz
+  cpan> force test Baz
+  cpan> force install Acme::Meta
+
+Each I<forced> command is executed with the corresponding part of its
+memory erased.
+
+The C<fforce> pragma is a variant that emulates a C<force get> which
+erases the entire memory followed by the action specified, effectively
+restarting the whole get/make/test/install procedure from scratch.
+
+=item Lockfile
+
+Interactive sessions maintain a lockfile, by default C<~/.cpan/.lock>.
+Batch jobs can run without a lockfile and not disturb each other.
+
+The shell offers to run in I<downgraded mode> when another process is
+holding the lockfile. This is an experimental feature that is not yet
+tested very well. This second shell then does not write the history
+file, does not use the metadata file, and has a different prompt.
+
+=item Signals
+
+CPAN.pm installs signal handlers for SIGINT and SIGTERM. While you are
+in the cpan-shell, it is intended that you can press C<^C> anytime and
+return to the cpan-shell prompt. A SIGTERM will cause the cpan-shell
+to clean up and leave the shell loop. You can emulate the effect of a
+SIGTERM by sending two consecutive SIGINTs, which usually means by
+pressing C<^C> twice.
+
+CPAN.pm ignores SIGPIPE. If the user sets C<inactivity_timeout>, a
+SIGALRM is used during the run of the C<perl Makefile.PL> or C<perl
+Build.PL> subprocess. A SIGALRM is also used during module version
+parsing, and is controlled by C<version_timeout>.
+
+=back
+
+=head2 CPAN::Shell
+
+The commands available in the shell interface are methods in
+the package CPAN::Shell. If you enter the shell command, your
+input is split by the Text::ParseWords::shellwords() routine, which
+acts like most shells do. The first word is interpreted as the
+method to be invoked, and the rest of the words are treated as the method's arguments.
+Continuation lines are supported by ending a line with a
+literal backslash.
+
+=head2 autobundle
+
+C<autobundle> writes a bundle file into the
+C<$CPAN::Config-E<gt>{cpan_home}/Bundle> directory. The file contains
+a list of all modules that are both available from CPAN and currently
+installed within @INC. Duplicates of each distribution are suppressed.
+The name of the bundle file is based on the current date and a
+counter, e.g. F<Bundle/Snapshot_2012_05_21_00.pm>. This is installed
+again by running C<cpan Bundle::Snapshot_2012_05_21_00>, or installing
+C<Bundle::Snapshot_2012_05_21_00> from the CPAN shell.
+
+Return value: path to the written file.
+
+=head2 hosts
+
+Note: this feature is still in alpha state and may change in future
+versions of CPAN.pm
+
+This commands provides a statistical overview over recent download
+activities. The data for this is collected in the YAML file
+C<FTPstats.yml> in your C<cpan_home> directory. If no YAML module is
+configured or YAML not installed, no stats are provided.
+
+=over
+
+=item install_tested
+
+Install all distributions that have been tested successfully but have
+not yet been installed. See also C<is_tested>.
+
+=item is_tested
+
+List all build directories of distributions that have been tested
+successfully but have not yet been installed. See also
+C<install_tested>.
+
+=back
+
+=head2 mkmyconfig
+
+mkmyconfig() writes your own CPAN::MyConfig file into your C<~/.cpan/>
+directory so that you can save your own preferences instead of the
+system-wide ones.
+
+=head2 r [Module|/Regexp/]...
+
+scans current perl installation for modules that have a newer version
+available on CPAN and provides a list of them. If called without
+argument, all potential upgrades are listed; if called with arguments
+the list is filtered to the modules and regexps given as arguments.
+
+The listing looks something like this:
+
+  Package namespace         installed    latest  in CPAN file
+  CPAN                        1.94_64    1.9600  ANDK/CPAN-1.9600.tar.gz
+  CPAN::Reporter               1.1801    1.1902  DAGOLDEN/CPAN-Reporter-1.1902.tar.gz

+
+It suppresses duplicates in the column C<in CPAN file> such that
+distributions with many upgradeable modules are listed only once.
+
+Note that the list is not sorted.
+
+=head2 recent ***EXPERIMENTAL COMMAND***
+
+The C<recent> command downloads a list of recent uploads to CPAN and
+displays them I<slowly>. While the command is running, a $SIG{INT}
+exits the loop after displaying the current item.
+
+B<Note>: This command requires XML::LibXML installed.
+
+B<Note>: This whole command currently is just a hack and will
+probably change in future versions of CPAN.pm, but the general
+approach will likely remain.
+
+B<Note>: See also L<smoke>
+
+=head2 recompile
+
+recompile() is a special command that takes no argument and
+runs the make/test/install cycle with brute force over all installed
+dynamically loadable extensions (a.k.a. XS modules) with 'force' in
+effect. The primary purpose of this command is to finish a network
+installation. Imagine you have a common source tree for two different
+architectures. You decide to do a completely independent fresh
+installation. You start on one architecture with the help of a Bundle
+file produced earlier. CPAN installs the whole Bundle for you, but
+when you try to repeat the job on the second architecture, CPAN
+responds with a C<"Foo up to date"> message for all modules. So you
+invoke CPAN's recompile on the second architecture and you're done.
+
+Another popular use for C<recompile> is to act as a rescue in case your
+perl breaks binary compatibility. If one of the modules that CPAN uses
+is in turn depending on binary compatibility (so you cannot run CPAN
+commands), then you should try the CPAN::Nox module for recovery.
+
+=head2 report Bundle|Distribution|Module
+
+The C<report> command temporarily turns on the C<test_report> config
+variable, then runs the C<force test> command with the given
+arguments. The C<force> pragma reruns the tests and repeats
+every step that might have failed before.
+
+=head2 smoke ***EXPERIMENTAL COMMAND***
+
+B<*** WARNING: this command downloads and executes software from CPAN to
+your computer of completely unknown status. You should never do
+this with your normal account and better have a dedicated well
+separated and secured machine to do this. ***>
+
+The C<smoke> command takes the list of recent uploads to CPAN as
+provided by the C<recent> command and tests them all. While the
+command is running $SIG{INT} is defined to mean that the current item
+shall be skipped.
+
+B<Note>: This whole command currently is just a hack and will
+probably change in future versions of CPAN.pm, but the general
+approach will likely remain.
+
+B<Note>: See also L<recent>
+
+=head2 upgrade [Module|/Regexp/]...
+
+The C<upgrade> command first runs an C<r> command with the given
+arguments and then installs the newest versions of all modules that
+were listed by that.
+
+=head2 The four C<CPAN::*> Classes: Author, Bundle, Module, Distribution
+
+Although it may be considered internal, the class hierarchy does matter
+for both users and programmer. CPAN.pm deals with the four
+classes mentioned above, and those classes all share a set of methods. Classical
+single polymorphism is in effect. A metaclass object registers all
+objects of all kinds and indexes them with a string. The strings
+referencing objects have a separated namespace (well, not completely
+separated):
+
+         Namespace                         Class
+
+   words containing a "/" (slash)      Distribution
+    words starting with Bundle::          Bundle
+          everything else            Module or Author
+
+Modules know their associated Distribution objects. They always refer
+to the most recent official release. Developers may mark their releases
+as unstable development versions (by inserting an underscore into the
+module version number which will also be reflected in the distribution
+name when you run 'make dist'), so the really hottest and newest
+distribution is not always the default.  If a module Foo circulates
+on CPAN in both version 1.23 and 1.23_90, CPAN.pm offers a convenient
+way to install version 1.23 by saying
+
+    install Foo
+
+This would install the complete distribution file (say
+BAR/Foo-1.23.tar.gz) with all accompanying material. But if you would
+like to install version 1.23_90, you need to know where the
+distribution file resides on CPAN relative to the authors/id/
+directory. If the author is BAR, this might be BAR/Foo-1.23_90.tar.gz;
+so you would have to say
+
+    install BAR/Foo-1.23_90.tar.gz
+
+The first example will be driven by an object of the class
+CPAN::Module, the second by an object of class CPAN::Distribution.
+
+=head2 Integrating local directories
+
+Note: this feature is still in alpha state and may change in future
+versions of CPAN.pm
+
+Distribution objects are normally distributions from the CPAN, but
+there is a slightly degenerate case for Distribution objects, too, of
+projects held on the local disk. These distribution objects have the
+same name as the local directory and end with a dot. A dot by itself
+is also allowed for the current directory at the time CPAN.pm was
+used. All actions such as C<make>, C<test>, and C<install> are applied
+directly to that directory. This gives the command C<cpan .> an
+interesting touch: while the normal mantra of installing a CPAN module
+without CPAN.pm is one of
+
+    perl Makefile.PL                 perl Build.PL
+           ( go and get prerequisites )
+    make                             ./Build
+    make test                        ./Build test
+    make install                     ./Build install
+
+the command C<cpan .> does all of this at once. It figures out which
+of the two mantras is appropriate, fetches and installs all
+prerequisites, takes care of them recursively, and finally finishes the
+installation of the module in the current directory, be it a CPAN
+module or not.
+
+The typical usage case is for private modules or working copies of
+projects from remote repositories on the local disk.
+
+=head2 Redirection
+
+The usual shell redirection symbols C< | > and C<< > >> are recognized
+by the cpan shell B<only when surrounded by whitespace>. So piping to
+pager or redirecting output into a file works somewhat as in a normal
+shell, with the stipulation that you must type extra spaces.
+
+=head2 Plugin support ***EXPERIMENTAL***
+
+Plugins are objects that implement any of currently eight methods:
+
+  pre_get
+  post_get
+  pre_make
+  post_make
+  pre_test
+  post_test
+  pre_install
+  post_install
+
+The C<plugin_list> configuration parameter holds a list of strings of
+the form
+
+  Modulename=arg0,arg1,arg2,arg3,...
+
+eg:
+
+  CPAN::Plugin::Flurb=dir,/opt/pkgs/flurb/raw,verbose,1
+
+At run time, each listed plugin is instantiated as a singleton object
+by running the equivalent of this pseudo code:
+
+  my $plugin = <string representation from config>;
+  <generate Modulename and arguments from $plugin>;
+  my $p = $instance{$plugin} ||= Modulename->new($arg0,$arg1,...);
+
+The generated singletons are kept around from instantiation until the
+end of the shell session. <plugin_list> can be reconfigured at any
+time at run time. While the cpan shell is running, it checks all
+activated plugins at each of the 8 reference points listed above and
+runs the respective method if it is implemented for that object. The
+method is called with the active CPAN::Distribution object passed in
+as an argument.
+
+=head1 CONFIGURATION
+
+When the CPAN module is used for the first time, a configuration
+dialogue tries to determine a couple of site specific options. The
+result of the dialog is stored in a hash reference C< $CPAN::Config >
+in a file CPAN/Config.pm.
+
+Default values defined in the CPAN/Config.pm file can be
+overridden in a user specific file: CPAN/MyConfig.pm. Such a file is
+best placed in C<$HOME/.cpan/CPAN/MyConfig.pm>, because C<$HOME/.cpan> is
+added to the search path of the CPAN module before the use() or
+require() statements. The mkmyconfig command writes this file for you.
+
+The C<o conf> command has various bells and whistles:
+
+=over
+
+=item completion support
+
+If you have a ReadLine module installed, you can hit TAB at any point
+of the commandline and C<o conf> will offer you completion for the
+built-in subcommands and/or config variable names.
+
+=item displaying some help: o conf help
+
+Displays a short help
+
+=item displaying current values: o conf [KEY]
+
+Displays the current value(s) for this config variable. Without KEY,
+displays all subcommands and config variables.
+
+Example:
+
+  o conf shell
+
+If KEY starts and ends with a slash, the string in between is
+treated as a regular expression and only keys matching this regexp
+are displayed
+
+Example:
+
+  o conf /color/
+
+=item changing of scalar values: o conf KEY VALUE
+
+Sets the config variable KEY to VALUE. The empty string can be
+specified as usual in shells, with C<''> or C<"">
+
+Example:
+
+  o conf wget /usr/bin/wget
+
+=item changing of list values: o conf KEY SHIFT|UNSHIFT|PUSH|POP|SPLICE|LIST
+
+If a config variable name ends with C<list>, it is a list. C<o conf
+KEY shift> removes the first element of the list, C<o conf KEY pop>
+removes the last element of the list. C<o conf KEYS unshift LIST>
+prepends a list of values to the list, C<o conf KEYS push LIST>
+appends a list of valued to the list.
+
+Likewise, C<o conf KEY splice LIST> passes the LIST to the corresponding
+splice command.
+
+Finally, any other list of arguments is taken as a new list value for
+the KEY variable discarding the previous value.
+
+Examples:
+
+  o conf urllist unshift http://cpan.dev.local/CPAN
+  o conf urllist splice 3 1
+  o conf urllist http://cpan1.local http://cpan2.local ftp://ftp.perl.org
+
+=item reverting to saved: o conf defaults
+
+Reverts all config variables to the state in the saved config file.
+
+=item saving the config: o conf commit
+
+Saves all config variables to the current config file (CPAN/Config.pm
+or CPAN/MyConfig.pm that was loaded at start).
+
+=back
+
+The configuration dialog can be started any time later again by
+issuing the command C< o conf init > in the CPAN shell. A subset of
+the configuration dialog can be run by issuing C<o conf init WORD>
+where WORD is any valid config variable or a regular expression.

+To specify a MATCH the argument must be enclosed by slashes.
+
+Examples:
+
+  o conf init ftp_passive ftp_proxy

+
+Note: this method of setting config variables often provides more
+explanation about the functioning of a variable than the manpage.
+
+=back
+
+=head2 CPAN::anycwd($path): Note on config variable getcwd
+
+CPAN.pm changes the current working directory often and needs to
+determine its own current working directory. By default it uses
+Cwd::cwd, but if for some reason this doesn't work on your system,
+configure alternatives according to the following table:
+
+=over 4
+
+=item cwd
+
+Calls Cwd::cwd
+
+=item getcwd
+
+Calls Cwd::getcwd
+
+=item fastcwd
+
+Calls Cwd::fastcwd
+
+=item getdcwd
+
+Calls Cwd::getdcwd
+
+=item backtickcwd
+
+Calls the external command cwd.
+
+=back
+
+=head2 Note on the format of the urllist parameter
+
+urllist parameters are URLs according to RFC 1738. We do a little
+guessing if your URL is not compliant, but if you have problems with
+C<file> URLs, please try the correct format. Either:
+
+    file://localhost/whatever/ftp/pub/CPAN/
+
+or
+
+    file:///home/ftp/pub/CPAN/
+
+=head2 The urllist parameter has CD-ROM support
+
+The C<urllist> parameter of the configuration table contains a list of
+URLs used for downloading. If the list contains any
+C<file> URLs, CPAN always tries there first. This
+feature is disabled for index files. So the recommendation for the
+owner of a CD-ROM with CPAN contents is: include your local, possibly
+outdated CD-ROM as a C<file> URL at the end of urllist, e.g.
+
+  o conf urllist push file://localhost/CDROM/CPAN
+
+CPAN.pm will then fetch the index files from one of the CPAN sites
+that come at the beginning of urllist. It will later check for each
+module to see whether there is a local copy of the most recent version.
+
+Another peculiarity of urllist is that the site that we could
+successfully fetch the last file from automatically gets a preference
+token and is tried as the first site for the next request. So if you
+add a new site at runtime it may happen that the previously preferred
+site will be tried another time. This means that if you want to disallow
+a site for the next transfer, it must be explicitly removed from
+urllist.
+
+=head2 Maintaining the urllist parameter
+
+If you have YAML.pm (or some other YAML module configured in
+C<yaml_module>) installed, CPAN.pm collects a few statistical data
+about recent downloads. You can view the statistics with the C<hosts>
+command or inspect them directly by looking into the C<FTPstats.yml>
+file in your C<cpan_home> directory.
+
+To get some interesting statistics, it is recommended that
+C<randomize_urllist> be set; this introduces some amount of
+randomness into the URL selection.
+
+=head2 The C<requires> and C<build_requires> dependency declarations
+
+Since CPAN.pm version 1.88_51 modules declared as C<build_requires> by
+a distribution are treated differently depending on the config
+variable C<build_requires_install_policy>. By setting
+C<build_requires_install_policy> to C<no>, such a module is not
+installed. It is only built and tested, and then kept in the list of
+tested but uninstalled modules. As such, it is available during the
+build of the dependent module by integrating the path to the
+C<blib/arch> and C<blib/lib> directories in the environment variable
+PERL5LIB. If C<build_requires_install_policy> is set to C<yes>, then
+both modules declared as C<requires> and those declared as
+C<build_requires> are treated alike. By setting to C<ask/yes> or
+C<ask/no>, CPAN.pm asks the user and sets the default accordingly.
+
+=head2 Configuration of the allow_installing_* parameters
+
+The C<allow_installing_*> parameters are evaluated during
+the C<make> phase. If set to C<yes>, they allow the testing and the installation of
+the current distro and otherwise have no effect. If set to C<no>, they
+may abort the build (preventing testing and installing), depending on the contents of the
+C<blib/> directory. The C<blib/> directory is the directory that holds
+all the files that would usually be installed in the C<install> phase.
+
+C<allow_installing_outdated_dists> compares the C<blib/> directory with the CPAN index.
+If it finds something there that belongs, according to the index, to a different
+dist, it aborts the current build.
+
+C<allow_installing_module_downgrades> compares the C<blib/> directory
+with already installed modules, actually their version numbers, as
+determined by ExtUtils::MakeMaker or equivalent. If a to-be-installed
+module would downgrade an already installed module, the current build
+is aborted.
+
+An interesting twist occurs when a distroprefs document demands the
+installation of an outdated dist via goto while
+C<allow_installing_outdated_dists> forbids it. Without additional
+provisions, this would let the C<allow_installing_outdated_dists>
+win and the distroprefs lose. So the proper arrangement in such a case
+is to write a second distroprefs document for the distro that C<goto>
+points to and overrule the C<cpanconfig> there. E.g.:
+
+  ---
+  match:
+    distribution: "^MAUKE/Keyword-Simple-0.04.tar.gz"
+  goto: "MAUKE/Keyword-Simple-0.03.tar.gz"
+  ---
+  match:
+    distribution: "^MAUKE/Keyword-Simple-0.03.tar.gz"
+  cpanconfig:
+    allow_installing_outdated_dists: yes
+
+=head2 Configuration for individual distributions (I<Distroprefs>)
+
+(B<Note:> This feature has been introduced in CPAN.pm 1.8854)
+
+Distributions on CPAN usually behave according to what we call the
+CPAN mantra. Or since the advent of Module::Build we should talk about
+two mantras:
+
+    perl Makefile.PL     perl Build.PL
+    make                 ./Build
+    make test            ./Build test
+    make install         ./Build install
+
+But some modules cannot be built with this mantra. They try to get
+some extra data from the user via the environment, extra arguments, or
+interactively--thus disturbing the installation of large bundles like
+Phalanx100 or modules with many dependencies like Plagger.
+
+The distroprefs system of C<CPAN.pm> addresses this problem by
+allowing the user to specify extra informations and recipes in YAML
+files to either
+
+=over
+
+=item
+
+pass additional arguments to one of the four commands,
+
+=item
+
+set environment variables
+
+=item
+
+instantiate an Expect object that reads from the console, waits for
+some regular expressions and enters some answers
+
+=item
+
+temporarily override assorted C<CPAN.pm> configuration variables
+
+=item
+
+specify dependencies the original maintainer forgot
+
+=item
+
+disable the installation of an object altogether
+
+=back
+
+See the YAML and Data::Dumper files that come with the C<CPAN.pm>
+distribution in the C<distroprefs/> directory for examples.
+
+=head2 Filenames
+
+The YAML files themselves must have the C<.yml> extension; all other
+files are ignored (for two exceptions see I<Fallback Data::Dumper and
+Storable> below). The containing directory can be specified in
+C<CPAN.pm> in the C<prefs_dir> config variable. Try C<o conf init
+prefs_dir> in the CPAN shell to set and activate the distroprefs
+system.
+
+Every YAML file may contain arbitrary documents according to the YAML
+specification, and every document is treated as an entity that
+can specify the treatment of a single distribution.
+
+Filenames can be picked arbitrarily; C<CPAN.pm> always reads
+all files (in alphabetical order) and takes the key C<match> (see
+below in I<Language Specs>) as a hashref containing match criteria
+that determine if the current distribution matches the YAML document
+or not.
+
+=head2 Fallback Data::Dumper and Storable
+
+If neither your configured C<yaml_module> nor YAML.pm is installed,
+CPAN.pm falls back to using Data::Dumper and Storable and looks for
+files with the extensions C<.dd> or C<.st> in the C<prefs_dir>
+directory. These files are expected to contain one or more hashrefs.
+For Data::Dumper generated files, this is expected to be done with by
+defining C<$VAR1>, C<$VAR2>, etc. The YAML shell would produce these
+with the command
+
+    ysh < somefile.yml > somefile.dd
+
+For Storable files the rule is that they must be constructed such that
+C<Storable::retrieve(file)> returns an array reference and the array
+elements represent one distropref object each. The conversion from
+YAML would look like so:
+
+    perl -MYAML=LoadFile -MStorable=nstore -e '
+        @y=LoadFile(shift);
+        nstore(\@y, shift)' somefile.yml somefile.st
+
+In bootstrapping situations it is usually sufficient to translate only
+a few YAML files to Data::Dumper for crucial modules like
+C<YAML::Syck>, C<YAML.pm> and C<Expect.pm>. If you prefer Storable
+over Data::Dumper, remember to pull out a Storable version that writes
+an older format than all the other Storable versions that will need to
+read them.

+with the exception of C<eexpect> which can be used instead of
+C<expect>.

+
+All three types, namely C<configure_requires>, C<build_requires>, and
+C<requires> are supported in the way specified in the META.yml
+specification. The current implementation I<merges> the specified

+=item install [hash]
+
+Processing instructions for the C<make install> or C<./Build install>
+phase of the CPAN mantra. See below under I<Processing Instructions>.
+
+=item make [hash]
+
+Processing instructions for the C<make> or C<./Build> phase of the
+CPAN mantra. See below under I<Processing Instructions>.
+
+=item match [hash]
+
+A hashref with one or more of the keys C<distribution>, C<module>,
+C<perl>, C<perlconfig>, and C<env> that specify whether a document is
+targeted at a specific CPAN distribution or installation.
+Keys prefixed with C<not_> negates the corresponding match.
+
+The corresponding values are interpreted as regular expressions. The
+C<distribution> related one will be matched against the canonical
+distribution name, e.g. "AUTHOR/Foo-Bar-3.14.tar.gz".
+
+The C<module> related one will be matched against I<all> modules
+contained in the distribution until one module matches.
+
+The C<perl> related one will be matched against C<$^X> (but with the
+absolute path).
+
+The value associated with C<perlconfig> is itself a hashref that is
+matched against corresponding values in the C<%Config::Config> hash
+living in the C<Config.pm> module.
+Keys prefixed with C<not_> negates the corresponding match.
+
+The value associated with C<env> is itself a hashref that is
+matched against corresponding values in the C<%ENV> hash.
+Keys prefixed with C<not_> negates the corresponding match.
+
+If more than one restriction of C<module>, C<distribution>, etc. is
+specified, the results of the separately computed match values must
+all match. If so, the hashref represented by the
+YAML document is returned as the preference structure for the current
+distribution.
+
+=item patches [array]
+
+An array of patches on CPAN or on the local disk to be applied in
+order via an external patch program. If the value for the C<-p>
+parameter is C<0> or C<1> is determined by reading the patch
+beforehand. The path to each patch is either an absolute path on the
+local filesystem or relative to a patch directory specified in the
+C<patches_dir> configuration variable or in the format of a canonical
+distro name. For examples please consult the distroprefs/ directory in
+the CPAN.pm distribution (these examples are not installed by
+default).
+
+Note: if the C<applypatch> program is installed and C<CPAN::Config>
+knows about it B<and> a patch is written by the C<makepatch> program,
+then C<CPAN.pm> lets C<applypatch> apply the patch. Both C<makepatch>
+and C<applypatch> are available from CPAN in the C<JV/makepatch-*>

+During execution, the environment variable PERL is set
+to $^X (but with an absolute path). If C<commandline> is specified,
+C<args> is not used.
+
+=item eexpect [hash]
+
+Extended C<expect>. This is a hash reference with four allowed keys,
+C<mode>, C<timeout>, C<reuse>, and C<talk>.
+
+You must install the C<Expect> module to use C<eexpect>. CPAN.pm
+does not install it for you.
+
+C<mode> may have the values C<deterministic> for the case where all
+questions come in the order written down and C<anyorder> for the case
+where the questions may come in any order. The default mode is
+C<deterministic>.
+
+C<timeout> denotes a timeout in seconds. Floating-point timeouts are
+OK. With C<mode=deterministic>, the timeout denotes the
+timeout per question; with C<mode=anyorder> it denotes the
+timeout per byte received from the stream or questions.
+
+C<talk> is a reference to an array that contains alternating questions
+and answers. Questions are regular expressions and answers are literal
+strings. The Expect module watches the stream from the
+execution of the external program (C<perl Makefile.PL>, C<perl
+Build.PL>, C<make>, etc.).
+
+For C<mode=deterministic>, the CPAN.pm injects the
+corresponding answer as soon as the stream matches the regular expression.
+
+For C<mode=anyorder> CPAN.pm answers a question as soon
+as the timeout is reached for the next byte in the input stream. In
+this mode you can use the C<reuse> parameter to decide what will
+happen with a question-answer pair after it has been used. In the
+default case (reuse=0) it is removed from the array, avoiding being
+used again accidentally. If you want to answer the
+question C<Do you really want to do that> several times, then it must
+be included in the array at least as often as you want this answer to
+be given. Setting the parameter C<reuse> to 1 makes this repetition
+unnecessary.
+
+=item env [hash]
+
+Environment variables to be set during the command
+
+=item expect [array]
+
+You must install the C<Expect> module to use C<expect>. CPAN.pm
+does not install it for you.
+
+C<< expect: <array> >> is a short notation for this C<eexpect>:
+
+	eexpect:
+		mode: deterministic
+		timeout: 15
+		talk: <array>

+
+=head2 Schema verification with C<Kwalify>
+
+If you have the C<Kwalify> module installed (which is part of the
+Bundle::CPANxxl), then all your distroprefs files are checked for
+syntactic correctness.
+
+=head2 Example Distroprefs Files
+
+C<CPAN.pm> comes with a collection of example YAML files. Note that these
+are really just examples and should not be used without care because
+they cannot fit everybody's purpose. After all, the authors of the
+packages that ask questions had a need to ask, so you should watch
+their questions and adjust the examples to your environment and your
+needs. You have been warned:-)
+
+=head1 PROGRAMMER'S INTERFACE
+
+If you do not enter the shell, shell commands are
+available both as methods (C<CPAN::Shell-E<gt>install(...)>) and as
+functions in the calling package (C<install(...)>).  Before calling low-level
+commands, it makes sense to initialize components of CPAN you need, e.g.:
+
+  CPAN::HandleConfig->load;
+  CPAN::Shell::setup_output;
+  CPAN::Index->reload;
+
+High-level commands do such initializations automatically.
+
+There's currently only one class that has a stable interface -
+CPAN::Shell. All commands that are available in the CPAN shell are
+methods of the class CPAN::Shell. The arguments on the commandline are
+passed as arguments to the method.
+
+So if you take for example the shell command
+
+  notest install A B C
+
+the actually executed command is
+
+  CPAN::Shell->notest("install","A","B","C");
+
+Each of the commands that produce listings of modules (C<r>,
+C<autobundle>, C<u>) also return a list of the IDs of all modules
+within the list.
+
+=over 2
+
+=item expand($type,@things)
+
+The IDs of all objects available within a program are strings that can
+be expanded to the corresponding real objects with the
+C<CPAN::Shell-E<gt>expand("Module",@things)> method. Expand returns a
+list of CPAN::Module objects according to the C<@things> arguments
+given. In scalar context, it returns only the first element of the
+list.
+
+=item expandany(@things)
+
+Like expand, but returns objects of the appropriate type, i.e.
+CPAN::Bundle objects for bundles, CPAN::Module objects for modules, and
+CPAN::Distribution objects for distributions. Note: it does not expand
+to CPAN::Author objects.
+
+=item Programming Examples
+
+This enables the programmer to do operations that combine
+functionalities that are available in the shell.
+
+    # install everything that is outdated on my disk:
+    perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'
+
+    # install my favorite programs if necessary:
+    for $mod (qw(Net::FTP Digest::SHA Data::Dumper)) {
+        CPAN::Shell->install($mod);
+    }
+
+    # list all modules on my disk that have no VERSION number
+    for $mod (CPAN::Shell->expand("Module","/./")) {
+        next unless $mod->inst_file;
+        # MakeMaker convention for undefined $VERSION:
+        next unless $mod->inst_version eq "undef";
+        print "No VERSION in ", $mod->id, "\n";
+    }
+
+    # find out which distribution on CPAN contains a module:
+    print CPAN::Shell->expand("Module","Apache::Constants")->cpan_file
+
+Or if you want to schedule a I<cron> job to watch CPAN, you could list
+all modules that need updating. First a quick and dirty way:
+
+    perl -e 'use CPAN; CPAN::Shell->r;'
+
+If you don't want any output should all modules be
+up to date, parse the output of above command for the regular
+expression C</modules are up to date/> and decide to mail the output
+only if it doesn't match.
+
+If you prefer to do it more in a programmerish style in one single
+process, something like this may better suit you:
+
+  # list all modules on my disk that have newer versions on CPAN
+  for $mod (CPAN::Shell->expand("Module","/./")) {
+    next unless $mod->inst_file;
+    next if $mod->uptodate;
+    printf "Module %s is installed as %s, could be updated to %s from CPAN\n",
+        $mod->id, $mod->inst_version, $mod->cpan_version;
+  }
+
+If that gives too much output every day, you may want to
+watch only for three modules. You can write
+
+  for $mod (CPAN::Shell->expand("Module","/Apache|LWP|CGI/")) {
+
+as the first line instead. Or you can combine some of the above
+tricks:
+
+  # watch only for a new mod_perl module
+  $mod = CPAN::Shell->expand("Module","mod_perl");
+  exit if $mod->uptodate;
+  # new mod_perl arrived, let me know all update recommendations
+  CPAN::Shell->r;

+
+=item CPAN::Distribution::install()
+
+Changes to the directory where the distribution has been unpacked and

+alphabetically, and the canonical distro name (e.g.
+AUTHOR/Foo-Bar-3.14.tar.gz) is matched against the regular expressions
+stored in the $root->{match}{distribution} attribute value.
+Additionally all module names contained in a distribution are matched
+against the regular expressions in the $root->{match}{module} attribute
+value. The two match values are ANDed together. Each of the two

+Currently the cache manager only keeps track of the build directory
+($CPAN::Config->{build_dir}). It is a simple FIFO mechanism that
+deletes complete directories below C<build_dir> as soon as the size of
+all directories there gets bigger than $CPAN::Config->{build_cache}
+(in MB). The contents of this cache may be used for later
+re-installations that you intend to do manually, but will never be
+trusted by CPAN itself. This is due to the fact that the user might
+use these directories for building modules on different architectures.
+
+There is another directory ($CPAN::Config->{keep_source_where}) where
+the original distribution files are kept. This directory is not
+covered by the cache manager and must be controlled by the user. If
+you choose to have the same directory as build_dir and as
+keep_source_where directory, then your sources will be deleted with
+the same fifo mechanism.
+
+=head2 Bundles
+
+A bundle is just a perl module in the namespace Bundle:: that does not
+define any functions or methods. It usually only contains documentation.
+
+It starts like a perl module with a package declaration and a $VERSION
+variable. After that the pod section looks like any other pod with the
+only difference being that I<one special pod section> exists starting with
+(verbatim):
+
+    =head1 CONTENTS
+
+In this pod section each line obeys the format
+
+        Module_Name [Version_String] [- optional text]
+
+The only required part is the first field, the name of a module
+(e.g. Foo::Bar, i.e. I<not> the name of the distribution file). The rest
+of the line is optional. The comment part is delimited by a dash just
+as in the man page header.
+
+The distribution of a bundle should follow the same convention as
+other distributions.
+
+Bundles are treated specially in the CPAN package. If you say 'install
+Bundle::Tkkit' (assuming such a bundle exists), CPAN will install all
+the modules in the CONTENTS section of the pod. You can install your
+own Bundles locally by placing a conformant Bundle file somewhere into
+your @INC path. The autobundle() command which is available in the
+shell interface does that for you by including all currently installed
+modules in a snapshot bundle file.
+
+=head1 PREREQUISITES
+
+The CPAN program is trying to depend on as little as possible so the
+user can use it in hostile environment. It works better the more goodies
+the environment provides. For example if you try in the CPAN shell
+
+  install Bundle::CPAN
+
+or
+
+  install Bundle::CPANxxl
+
+you will find the shell more convenient than the bare shell before.
+
+If you have a local mirror of CPAN and can access all files with
+"file:" URLs, then you only need a perl later than perl5.003 to run
+this module. Otherwise Net::FTP is strongly recommended. LWP may be
+required for non-UNIX systems, or if your nearest CPAN site is
+associated with a URL that is not C<ftp:>.
+
+If you have neither Net::FTP nor LWP, there is a fallback mechanism
+implemented for an external ftp command or for an external lynx
+command.
+
+=head1 UTILITIES
+
+=head2 Finding packages and VERSION
+
+This module presumes that all packages on CPAN
+
+=over 2
+
+=item *
+
+declare their $VERSION variable in an easy to parse manner. This
+prerequisite can hardly be relaxed because it consumes far too much
+memory to load all packages into the running program just to determine
+the $VERSION variable. Currently all programs that are dealing with
+version use something like this
+
+    perl -MExtUtils::MakeMaker -le \
+        'print MM->parse_version(shift)' filename
+
+If you are author of a package and wonder if your $VERSION can be
+parsed, please try the above method.
+
+=item *
+
+come as compressed or gzipped tarfiles or as zip files and contain a
+C<Makefile.PL> or C<Build.PL> (well, we try to handle a bit more, but
+with little enthusiasm).
+
+=back
+
+=head2 Debugging
+
+Debugging this module is more than a bit complex due to interference from
+the software producing the indices on CPAN, the mirroring process on CPAN,
+packaging, configuration, synchronicity, and even (gasp!) due to bugs
+within the CPAN.pm module itself.
+
+For debugging the code of CPAN.pm itself in interactive mode, some
+debugging aid can be turned on for most packages within
+CPAN.pm with one of
+
+=over 2
+
+=item o debug package...
+
+sets debug mode for packages.
+
+=item o debug -package...
+
+unsets debug mode for packages.
+
+=item o debug all
+
+turns debugging on for all packages.
+
+=item o debug number
+
+=back
+
+which sets the debugging packages directly. Note that C<o debug 0>
+turns debugging off.
+
+What seems a successful strategy is the combination of C<reload
+cpan> and the debugging switches. Add a new debug statement while
+running in the shell and then issue a C<reload cpan> and see the new
+debugging messages immediately without losing the current context.
+
+C<o debug> without an argument lists the valid package names and the
+current set of packages in debugging mode. C<o debug> has built-in
+completion support.
+
+For debugging of CPAN data there is the C<dump> command which takes
+the same arguments as make/test/install and outputs each object's
+Data::Dumper dump. If an argument looks like a perl variable and
+contains one of C<$>, C<@> or C<%>, it is eval()ed and fed to
+Data::Dumper directly.
+
+=head2 Floppy, Zip, Offline Mode
+
+CPAN.pm works nicely without network access, too. If you maintain machines
+that are not networked at all, you should consider working with C<file:>
+URLs. You'll have to collect your modules somewhere first. So
+you might use CPAN.pm to put together all you need on a networked
+machine. Then copy the $CPAN::Config->{keep_source_where} (but not
+$CPAN::Config->{build_dir}) directory on a floppy. This floppy is kind
+of a personal CPAN. CPAN.pm on the non-networked machines works nicely
+with this floppy. See also below the paragraph about CD-ROM support.
+
+=head2 Basic Utilities for Programmers
+
+=over 2
+
+=item has_inst($module)
+
+Returns true if the module is installed. Used to load all modules into
+the running CPAN.pm that are considered optional. The config variable
+C<dontload_list> intercepts the C<has_inst()> call such
+that an optional module is not loaded despite being available. For
+example, the following command will prevent C<YAML.pm> from being
+loaded:
+
+    cpan> o conf dontload_list push YAML
+
+See the source for details.
+
+=item use_inst($module)
+
+Similary to L<has_inst()> tries to load optional library but also dies if
+library is not available
+
+=item has_usable($module)
+
+Returns true if the module is installed and in a usable state. Only
+useful for a handful of modules that are used internally. See the
+source for details.
+
+=item instance($module)
+
+The constructor for all the singletons used to represent modules,
+distributions, authors, and bundles. If the object already exists, this
+method returns the object; otherwise, it calls the constructor.
+
+=item frontend()
+
+=item frontend($new_frontend)
+
+Getter/setter for frontend object. Method just allows to subclass CPAN.pm.
+
+=back
+
+=head1 SECURITY
+
+There's no strong security layer in CPAN.pm. CPAN.pm helps you to
+install foreign, unmasked, unsigned code on your machine. We compare
+to a checksum that comes from the net just as the distribution file
+itself. But we try to make it easy to add security on demand:
+
+=head2 Cryptographically signed modules
+
+Since release 1.77, CPAN.pm has been able to verify cryptographically
+signed module distributions using Module::Signature.  The CPAN modules
+can be signed by their authors, thus giving more security.  The simple
+unsigned MD5 checksums that were used before by CPAN protect mainly
+against accidental file corruption.
+
+You will need to have Module::Signature installed, which in turn
+requires that you have at least one of Crypt::OpenPGP module or the
+command-line F<gpg> tool installed.
+
+You will also need to be able to connect over the Internet to the public
+key servers, like pgp.mit.edu, and their port 11731 (the HKP protocol).
+
+The configuration parameter check_sigs is there to turn signature
+checking on or off.
+
+=head1 EXPORT
+
+Most functions in package CPAN are exported by default. The reason
+for this is that the primary use is intended for the cpan shell or for
+one-liners.
+
+=head1 ENVIRONMENT
+
+When the CPAN shell enters a subshell via the look command, it sets
+the environment CPAN_SHELL_LEVEL to 1, or increments that variable if it is
+already set.
+
+When CPAN runs, it sets the environment variable PERL5_CPAN_IS_RUNNING
+to the ID of the running process. It also sets
+PERL5_CPANPLUS_IS_RUNNING to prevent runaway processes which could
+happen with older versions of Module::Install.
+
+When running C<perl Makefile.PL>, the environment variable
+C<PERL5_CPAN_IS_EXECUTING> is set to the full path of the
+C<Makefile.PL> that is being executed. This prevents runaway processes
+with newer versions of Module::Install.
+
+When the config variable ftp_passive is set, all downloads will be run
+with the environment variable FTP_PASSIVE set to this value. This is
+in general a good idea as it influences both Net::FTP and LWP based
+connections. The same effect can be achieved by starting the cpan
+shell with this environment variable set. For Net::FTP alone, one can
+also always set passive mode by running libnetcfg.
+
+=head1 POPULATE AN INSTALLATION WITH LOTS OF MODULES
+
+Populating a freshly installed perl with one's favorite modules is pretty
+easy if you maintain a private bundle definition file. To get a useful
+blueprint of a bundle definition file, the command autobundle can be used
+on the CPAN shell command line. This command writes a bundle definition
+file for all modules installed for the current perl
+interpreter. It's recommended to run this command once only, and from then
+on maintain the file manually under a private name, say
+Bundle/my_bundle.pm. With a clever bundle file you can then simply say
+
+    cpan> install Bundle::my_bundle
+
+then answer a few questions and go out for coffee (possibly
+even in a different city).
+
+Maintaining a bundle definition file means keeping track of two
+things: dependencies and interactivity. CPAN.pm sometimes fails on
+calculating dependencies because not all modules define all MakeMaker
+attributes correctly, so a bundle definition file should specify
+prerequisites as early as possible. On the other hand, it's
+annoying that so many distributions need some interactive configuring. So
+what you can try to accomplish in your private bundle file is to have the
+packages that need to be configured early in the file and the gentle
+ones later, so you can go out for coffee after a few minutes and leave CPAN.pm
+to churn away unattended.
+
+=head1 WORKING WITH CPAN.pm BEHIND FIREWALLS
+
+Thanks to Graham Barr for contributing the following paragraphs about
+the interaction between perl, and various firewall configurations. For
+further information on firewalls, it is recommended to consult the
+documentation that comes with the I<ncftp> program. If you are unable to
+go through the firewall with a simple Perl setup, it is likely
+that you can configure I<ncftp> so that it works through your firewall.
+
+=head2 Three basic types of firewalls
+
+Firewalls can be categorized into three basic types.
+
+=over 4
+
+=item http firewall
+
+This is when the firewall machine runs a web server, and to access the
+outside world, you must do so via that web server. If you set environment
+variables like http_proxy or ftp_proxy to values beginning with http://,
+or in your web browser you've proxy information set, then you know
+you are running behind an http firewall.
+
+To access servers outside these types of firewalls with perl (even for
+ftp), you need LWP or HTTP::Tiny.
+
+=item ftp firewall
+
+This where the firewall machine runs an ftp server. This kind of
+firewall will only let you access ftp servers outside the firewall.
+This is usually done by connecting to the firewall with ftp, then
+entering a username like "user@outside.host.com".
+
+To access servers outside these type of firewalls with perl, you
+need Net::FTP.
+
+=item One-way visibility
+
+One-way visibility means these firewalls try to make themselves
+invisible to users inside the firewall. An FTP data connection is
+normally created by sending your IP address to the remote server and then
+listening for the return connection. But the remote server will not be able to
+connect to you because of the firewall. For these types of firewall,
+FTP connections need to be done in a passive mode.
+
+There are two that I can think off.
+
+=over 4
+
+=item SOCKS
+
+If you are using a SOCKS firewall, you will need to compile perl and link
+it with the SOCKS library.  This is what is normally called a 'socksified'
+perl. With this executable you will be able to connect to servers outside
+the firewall as if it were not there.
+
+=item IP Masquerade
+
+This is when the firewall implemented in the kernel (via NAT, or networking
+address translation), it allows you to hide a complete network behind one
+IP address. With this firewall no special compiling is needed as you can
+access hosts directly.
+
+For accessing ftp servers behind such firewalls you usually need to
+set the environment variable C<FTP_PASSIVE> or the config variable
+ftp_passive to a true value.
+
+=back
+
+=back
+
+=head2 Configuring lynx or ncftp for going through a firewall
+
+If you can go through your firewall with e.g. lynx, presumably with a
+command such as
+
+    /usr/local/bin/lynx -pscott:tiger
+
+then you would configure CPAN.pm with the command
+
+    o conf lynx "/usr/local/bin/lynx -pscott:tiger"
+
+That's all. Similarly for ncftp or ftp, you would configure something
+like
+
+    o conf ncftp "/usr/bin/ncftp -f /home/scott/ncftplogin.cfg"
+
+Your mileage may vary...
+
+=head1 FAQ
+
+=over 4
+
+=item 1)
+
+I installed a new version of module X but CPAN keeps saying,
+I have the old version installed
+
+Probably you B<do> have the old version installed. This can
+happen if a module installs itself into a different directory in the
+@INC path than it was previously installed. This is not really a
+CPAN.pm problem, you would have the same problem when installing the
+module manually. The easiest way to prevent this behaviour is to add
+the argument C<UNINST=1> to the C<make install> call, and that is why
+many people add this argument permanently by configuring
+
+  o conf make_install_arg UNINST=1
+
+=item 2)
+
+So why is UNINST=1 not the default?
+
+Because there are people who have their precise expectations about who
+may install where in the @INC path and who uses which @INC array. In
+fine tuned environments C<UNINST=1> can cause damage.
+
+=item 3)
+
+I want to clean up my mess, and install a new perl along with
+all modules I have. How do I go about it?
+
+Run the autobundle command for your old perl and optionally rename the
+resulting bundle file (e.g. Bundle/mybundle.pm), install the new perl
+with the Configure option prefix, e.g.
+
+    ./Configure -Dprefix=/usr/local/perl-5.6.78.9
+
+Install the bundle file you produced in the first step with something like
+
+    cpan> install Bundle::mybundle
+
+and you're done.
+
+=item 4)
+
+When I install bundles or multiple modules with one command
+there is too much output to keep track of.
+
+You may want to configure something like
+
+  o conf make_arg "| tee -ai /root/.cpan/logs/make.out"
+  o conf make_install_arg "| tee -ai /root/.cpan/logs/make_install.out"
+
+so that STDOUT is captured in a file for later inspection.
+
+
+=item 5)
+
+I am not root, how can I install a module in a personal directory?
+
+As of CPAN 1.9463, if you do not have permission to write the default perl
+library directories, CPAN's configuration process will ask you whether
+you want to bootstrap <local::lib>, which makes keeping a personal
+perl library directory easy.
+
+Another thing you should bear in mind is that the UNINST parameter can
+be dangerous when you are installing into a private area because you
+might accidentally remove modules that other people depend on that are
+not using the private area.
+
+=item 6)
+
+How to get a package, unwrap it, and make a change before building it?
+
+Have a look at the C<look> (!) command.
+
+=item 7)
+
+I installed a Bundle and had a couple of fails. When I
+retried, everything resolved nicely. Can this be fixed to work
+on first try?
+
+The reason for this is that CPAN does not know the dependencies of all
+modules when it starts out. To decide about the additional items to
+install, it just uses data found in the META.yml file or the generated
+Makefile. An undetected missing piece breaks the process. But it may
+well be that your Bundle installs some prerequisite later than some
+depending item and thus your second try is able to resolve everything.
+Please note, CPAN.pm does not know the dependency tree in advance and
+cannot sort the queue of things to install in a topologically correct
+order. It resolves perfectly well B<if> all modules declare the
+prerequisites correctly with the PREREQ_PM attribute to MakeMaker or
+the C<requires> stanza of Module::Build. For bundles which fail and
+you need to install often, it is recommended to sort the Bundle
+definition file manually.
+
+=item 8)
+
+In our intranet, we have many modules for internal use. How
+can I integrate these modules with CPAN.pm but without uploading
+the modules to CPAN?
+
+Have a look at the CPAN::Site module.
+
+=item 9)
+
+When I run CPAN's shell, I get an error message about things in my
+C</etc/inputrc> (or C<~/.inputrc>) file.
+
+These are readline issues and can only be fixed by studying readline
+configuration on your architecture and adjusting the referenced file
+accordingly. Please make a backup of the C</etc/inputrc> or C<~/.inputrc>
+and edit them. Quite often harmless changes like uppercasing or
+lowercasing some arguments solves the problem.
+
+=item 10)
+
+Some authors have strange characters in their names.
+
+Internally CPAN.pm uses the UTF-8 charset. If your terminal is
+expecting ISO-8859-1 charset, a converter can be activated by setting
+term_is_latin to a true value in your config file. One way of doing so
+would be
+
+    cpan> o conf term_is_latin 1
+
+If other charset support is needed, please file a bug report against
+CPAN.pm at rt.cpan.org and describe your needs. Maybe we can extend
+the support or maybe UTF-8 terminals become widely available.
+
+Note: this config variable is deprecated and will be removed in a
+future version of CPAN.pm. It will be replaced with the conventions
+around the family of $LANG and $LC_* environment variables.
+
+=item 11)
+
+When an install fails for some reason and then I correct the error
+condition and retry, CPAN.pm refuses to install the module, saying
+C<Already tried without success>.
+
+Use the force pragma like so
+
+  force install Foo::Bar
+
+Or you can use
+
+  look Foo::Bar
+
+and then C<make install> directly in the subshell.
+
+=item 12)
+
+How do I install a "DEVELOPER RELEASE" of a module?
+
+By default, CPAN will install the latest non-developer release of a
+module. If you want to install a dev release, you have to specify the
+partial path starting with the author id to the tarball you wish to
+install, like so:
+
+    cpan> install KWILLIAMS/Module-Build-0.27_07.tar.gz
+
+Note that you can use the C<ls> command to get this path listed.
+
+=item 13)
+
+How do I install a module and all its dependencies from the commandline,
+without being prompted for anything, despite my CPAN configuration
+(or lack thereof)?
+
+CPAN uses ExtUtils::MakeMaker's prompt() function to ask its questions, so
+if you set the PERL_MM_USE_DEFAULT environment variable, you shouldn't be
+asked any questions at all (assuming the modules you are installing are
+nice about obeying that variable as well):
+
+    % PERL_MM_USE_DEFAULT=1 perl -MCPAN -e 'install My::Module'
+
+=item 14)
+
+How do I create a Module::Build based Build.PL derived from an
+ExtUtils::MakeMaker focused Makefile.PL?
+
+http://search.cpan.org/dist/Module-Build-Convert/
+
+=item 15)
+
+I'm frequently irritated with the CPAN shell's inability to help me
+select a good mirror.
+
+CPAN can now help you select a "good" mirror, based on which ones have the
+lowest 'ping' round-trip times.  From the shell, use the command 'o conf init
+urllist' and allow CPAN to automatically select mirrors for you.
+
+Beyond that help, the urllist config parameter is yours. You can add and remove
+sites at will. You should find out which sites have the best up-to-dateness,
+bandwidth, reliability, etc. and are topologically close to you. Some people
+prefer fast downloads, others up-to-dateness, others reliability.  You decide
+which to try in which order.
+
+Henk P. Penning maintains a site that collects data about CPAN sites:
+
+  http://mirrors.cpan.org/
+
+Also, feel free to play with experimental features. Run
+
+  o conf init randomize_urllist ftpstats_period ftpstats_size
+
+and choose your favorite parameters. After a few downloads running the
+C<hosts> command will probably assist you in choosing the best mirror
+sites.
+
+=item 16)
+
+Why do I get asked the same questions every time I start the shell?
+
+You can make your configuration changes permanent by calling the
+command C<o conf commit>. Alternatively set the C<auto_commit>
+variable to true by running C<o conf init auto_commit> and answering
+the following question with yes.
+
+=item 17)
+
+Older versions of CPAN.pm had the original root directory of all
+tarballs in the build directory. Now there are always random
+characters appended to these directory names. Why was this done?
+
+The random characters are provided by File::Temp and ensure that each
+module's individual build directory is unique. This makes running
+CPAN.pm in concurrent processes simultaneously safe.
+
+=item 18)
+
+Speaking of the build directory. Do I have to clean it up myself?
+
+You have the choice to set the config variable C<scan_cache> to
+C<never>. Then you must clean it up yourself. The other possible
+values, C<atstart> and C<atexit> clean up the build directory when you
+start (or more precisely, after the first extraction into the build
+directory) or exit the CPAN shell, respectively. If you never start up
+the CPAN shell, you probably also have to clean up the build directory
+yourself.
+
+=item 19)
+
+How can I switch to sudo instead of local::lib?
+
+The following 5 environment veriables need to be reset to the previous
+values: PATH, PERL5LIB, PERL_LOCAL_LIB_ROOT, PERL_MB_OPT, PERL_MM_OPT;
+and these two CPAN.pm config variables must be reconfigured:
+make_install_make_command and mbuild_install_build_command. The five
+env variables have probably been overwritten in your $HOME/.bashrc or
+some equivalent. You either find them there and delete their traces
+and logout/login or you override them temporarily, depending on your
+exact desire. The two cpanpm config variables can be set with:
+
+  o conf init /install_.*_command/
+
+probably followed by
+
+  o conf commit
+
+=back
+
+=head1 COMPATIBILITY
+
+=head2 OLD PERL VERSIONS
+
+CPAN.pm is regularly tested to run under 5.005 and assorted
+newer versions. It is getting more and more difficult to get the
+minimal prerequisites working on older perls. It is close to
+impossible to get the whole Bundle::CPAN working there. If you're in
+the position to have only these old versions, be advised that CPAN is
+designed to work fine without the Bundle::CPAN installed.
+
+To get things going, note that GBARR/Scalar-List-Utils-1.18.tar.gz is
+compatible with ancient perls and that File::Temp is listed as a
+prerequisite but CPAN has reasonable workarounds if it is missing.
+
+=head2 CPANPLUS
+
+This module and its competitor, the CPANPLUS module, are both much
+cooler than the other. CPAN.pm is older. CPANPLUS was designed to be
+more modular, but it was never intended to be compatible with CPAN.pm.
+
+=head2 CPANMINUS
+
+In the year 2010 App::cpanminus was launched as a new approach to a
+cpan shell with a considerably smaller footprint. Very cool stuff.
+
+=head1 SECURITY ADVICE
+
+This software enables you to upgrade software on your computer and so
+is inherently dangerous because the newly installed software may
+contain bugs and may alter the way your computer works or even make it
+unusable. Please consider backing up your data before every upgrade.
+
+=head1 BUGS
+
+Please report bugs via L<http://rt.cpan.org/>
+
+Before submitting a bug, please make sure that the traditional method
+of building a Perl module package from a shell by following the
+installation instructions of that package still works in your
+environment.

+=head1 NAME
+
+ CPAN::Admin - A CPAN Shell for CPAN admins
+
+=head1 SYNOPSIS
+
+ perl -MCPAN::Admin -e shell
+
+=head1 STATUS
+
+Note: this module is currently not maintained. If you need it and fix
+it for your needs, please submit patches.
+
+=head1 DESCRIPTION
+
+CPAN::Admin is a subclass of CPAN that adds the commands C<register>
+and C<modsearch> to the CPAN shell.
+
+C<register> calls C<get> on the named module, assembles a couple of
+informations (description, language), and calls Netscape with the
+-remote argument so that a form is filled with all the assembled
+informations and the registration can be performed with a single
+click. If the command line has more than one argument, register does
+not run a C<get>, instead it interprets the rest of the line as DSLI
+status, description, and userid and sends them to netscape such that
+the form is again mostly filled and can be edited or confirmed with a
+single click. CPAN::Admin never performs the submission click for you,
+it is only intended to fill in the form on PAUSE and leave the
+confirmation to you.
+
+C<modsearch> simply passes the arguments to the search engine for the
+modules@perl.org mailing list at L<http://www.xray.mpe.mpg.de> where all
+registration requests are stored. It does so in the same way as
+register, namely with the C<netscape -remote> command.
+
+An experimental feature has also been added, namely to color already
+registered modules in listings. If you have L<Term::ANSIColor> installed,
+the u, r, and m commands will show already registered modules in
+green.
+
+=head1 PREREQUISITES
+
+L<URI::Escape>, a browser available in the path, the browser must
+understand the -remote switch (as far as I know, this is only
+available on UNIX); coloring of registered modules is only available
+if L<Term::ANSIColor> is installed.

+    use CPAN::Distroprefs;
+
+    my %info = (... distribution/environment info ...);
+
+    my $finder = CPAN::Distroprefs->find($prefs_dir, \%ext_map);
+
+    while (my $result = $finder->next) {
+
+        die $result->as_string if $result->is_fatal;
+
+        warn($result->as_string), next if $result->is_warning;
+
+        for my $pref (@{ $result->prefs }) {
+            if ($pref->matches(\%info)) {
+                return $pref;
+            }
+        }
+    }
+
+
+=head1 DESCRIPTION
+
+This module encapsulates reading L<Distroprefs|CPAN> and matching them against CPAN distributions.
+
+=head1 INTERFACE
+
+    my $finder = CPAN::Distroprefs->find($dir, \%ext_map);
+
+    while (my $result = $finder->next) { ... }
+
+Build an iterator which finds distroprefs files in the tree below the
+given directory. Within the tree directories matching C<m/^[._]/> are
+pruned.
+
+C<%ext_map> is a hashref whose keys are file extensions and whose values are
+modules used to load matching files:
+
+    {
+        'yml' => 'YAML::Syck',
+        'dd'  => 'Data::Dumper',
+        ...
+    }
+
+Each time C<< $finder->next >> is called, the iterator returns one of two
+possible values:
+
+=over
+
+=item * a CPAN::Distroprefs::Result object
+
+=item * C<undef>, indicating that no prefs files remain to be found
+
+=back
+
+=head1 RESULTS
+
+L<C<find()>|/INTERFACE> returns CPAN::Distroprefs::Result objects to
+indicate success or failure when reading a prefs file.
+
+=head2 Common
+
+All results share some common attributes:
+
+=head3 type
+
+C<success>, C<warning>, or C<fatal>
+
+=head3 file
+
+the file from which these prefs were read, or to which this error refers (relative filename)
+
+=head3 ext
+
+the file's extension, which determines how to load it
+
+=head3 dir
+
+the directory the file was read from
+
+=head3 abs
+
+the absolute path to the file
+
+=head2 Errors
+
+Error results (warning and fatal) contain:
+
+=head3 msg
+
+the error message (usually either C<$!> or a YAML error)
+
+=head2 Successes
+
+Success results contain:
+
+=head3 prefs
+
+an arrayref of CPAN::Distroprefs::Pref objects
+
+=head1 PREFS
+
+CPAN::Distroprefs::Pref objects represent individual distroprefs documents.
+They are constructed automatically as part of C<success> results from C<find()>.
+
+=head3 data
+
+the pref information as a hashref, suitable for e.g. passing to Kwalify
+
+=head3 match_attributes
+
+returns a list of the valid match attributes (see the Distroprefs section in L<CPAN>)
+
+currently: C<env perl perlconfig distribution module>
+
+=head3 has_any_match
+
+true if this pref has a 'match' attribute at all
+
+=head3 has_valid_subkeys
+
+true if this pref has a 'match' attribute and at least one valid match attribute
+
+=head3 matches
+
+  if ($pref->matches(\%arg)) { ... }
+
+true if this pref matches the passed-in hashref, which must have a value for
+each of the C<match_attributes> (above)

+=head1 NAME
+
+CPAN::FirstTime - Utility for CPAN::Config file Initialization
+
+=head1 SYNOPSIS
+
+CPAN::FirstTime::init()
+
+=head1 DESCRIPTION
+
+The init routine asks a few questions and writes a CPAN/Config.pm or
+CPAN/MyConfig.pm file (depending on what it is currently using).
+
+In the following all questions and explanations regarding config
+variables are collected.
+
+=cut
+
+# down until the next =back the manpage must be parsed by the program
+# because the text is used in the init dialogues.
+
+my @podpara = split /\n\n/, <<'=back';

+
+=item allow_installing_module_downgrades
+
+The CPAN shell can watch the C<blib/> directories that are built up
+before running C<make test> to determine whether the current
+distribution will end up with modules being overwritten with decreasing module version numbers. It
+can then let the build of this distro fail when it discovers a
+downgrade.
+
+Do you want to allow installing distros with decreasing module
+versions compared to what you have installed (yes, no, ask/yes,
+ask/no)?
+
+=item allow_installing_outdated_dists
+
+The CPAN shell can watch the C<blib/> directories that are built up
+before running C<make test> to determine whether the current
+distribution contains modules that are indexed with a distro with a
+higher distro-version number than the current one. It can
+then let the build of this distro fail when it would not represent the
+most up-to-date version of the distro.
+
+Note: choosing anything but 'yes' for this option will need
+CPAN::DistnameInfo being installed for taking effect.
+
+Do you want to allow installing distros that are not indexed as the
+highest distro-version for all contained modules (yes, no, ask/yes,
+ask/no)?
+
+=item auto_commit
+
+Normally CPAN.pm keeps config variables in memory and changes need to
+be saved in a separate 'o conf commit' command to make them permanent
+between sessions. If you set the 'auto_commit' option to true, changes
+to a config variable are always automatically committed to disk.
+
+Always commit changes to config variables to disk?
+
+=item build_cache
+
+CPAN.pm can limit the size of the disk area for keeping the build
+directories with all the intermediate files.
+
+Cache size for build directory (in MB)?
+
+=item build_dir
+
+Directory where the build process takes place?
+
+=item build_dir_reuse
+
+Until version 1.88 CPAN.pm never trusted the contents of the build_dir
+directory between sessions. Since 1.88_58 CPAN.pm has a YAML-based
+mechanism that makes it possible to share the contents of the
+build_dir/ directory between different sessions with the same version
+of perl. People who prefer to test things several days before
+installing will like this feature because it saves a lot of time.
+
+If you say yes to the following question, CPAN will try to store
+enough information about the build process so that it can pick up in
+future sessions at the same state of affairs as it left a previous
+session.
+
+Store and re-use state information about distributions between
+CPAN.pm sessions?
+
+=item build_requires_install_policy
+
+When a module declares another one as a 'build_requires' prerequisite
+this means that the other module is only needed for building or
+testing the module but need not be installed permanently. In this case
+you may wish to install that other module nonetheless or just keep it
+in the 'build_dir' directory to have it available only temporarily.
+Installing saves time on future installations but makes the perl
+installation bigger.
+
+You can choose if you want to always install (yes), never install (no)
+or be always asked. In the latter case you can set the default answer
+for the question to yes (ask/yes) or no (ask/no).
+
+Policy on installing 'build_requires' modules (yes, no, ask/yes,
+ask/no)?
+
+=item cache_metadata
+
+To considerably speed up the initial CPAN shell startup, it is
+possible to use Storable to create a cache of metadata. If Storable is
+not available, the normal index mechanism will be used.
+
+Note: this mechanism is not used when use_sqlite is on and SQLLite is
+running.
+
+Cache metadata (yes/no)?
+
+=item check_sigs
+
+CPAN packages can be digitally signed by authors and thus verified
+with the security provided by strong cryptography. The exact mechanism
+is defined in the Module::Signature module. While this is generally
+considered a good thing, it is not always convenient to the end user
+to install modules that are signed incorrectly or where the key of the
+author is not available or where some prerequisite for
+Module::Signature has a bug and so on.
+
+With the check_sigs parameter you can turn signature checking on and
+off. The default is off for now because the whole tool chain for the
+functionality is not yet considered mature by some. The author of
+CPAN.pm would recommend setting it to true most of the time and
+turning it off only if it turns out to be annoying.
+
+Note that if you do not have Module::Signature installed, no signature
+checks will be performed at all.
+
+Always try to check and verify signatures if a SIGNATURE file is in
+the package and Module::Signature is installed (yes/no)?
+
+=item cleanup_after_install
+
+Users who install modules and do not intend to look back, can free
+occupied disk space quickly by letting CPAN.pm cleanup each build
+directory immediately after a successful install.
+
+Remove build directory after a successful install? (yes/no)?
+
+=item colorize_output
+
+When you have Term::ANSIColor installed, you can turn on colorized
+output to have some visual differences between normal CPAN.pm output,
+warnings, debugging output, and the output of the modules being
+installed. Set your favorite colors after some experimenting with the
+Term::ANSIColor module.
+
+Please note that on Windows platforms colorized output also requires
+the Win32::Console::ANSI module.
+
+Do you want to turn on colored output?
+
+=item colorize_print
+
+Color for normal output?
+
+=item colorize_warn
+
+Color for warnings?
+
+=item colorize_debug
+
+Color for debugging messages?
+
+=item commandnumber_in_prompt
+
+The prompt of the cpan shell can contain the current command number
+for easier tracking of the session or be a plain string.
+
+Do you want the command number in the prompt (yes/no)?
+
+=item connect_to_internet_ok
+
+If you have never defined your own C<urllist> in your configuration
+then C<CPAN.pm> will be hesitant to use the built in default sites for
+downloading. It will ask you once per session if a connection to the
+internet is OK and only if you say yes, it will try to connect. But to
+avoid this question, you can choose your favorite download sites once
+and get away with it. Or, if you have no favorite download sites
+answer yes to the following question.
+
+If no urllist has been chosen yet, would you prefer CPAN.pm to connect
+to the built-in default sites without asking? (yes/no)?
+
+=item ftp_passive
+
+Shall we always set the FTP_PASSIVE environment variable when dealing
+with ftp download (yes/no)?
+
+=item ftpstats_period
+
+Statistics about downloads are truncated by size and period
+simultaneously.
+
+How many days shall we keep statistics about downloads?
+
+=item ftpstats_size
+
+Statistics about downloads are truncated by size and period
+simultaneously. Setting this to zero or negative disables download
+statistics.
+
+How many items shall we keep in the statistics about downloads?
+
+=item getcwd
+
+CPAN.pm changes the current working directory often and needs to
+determine its own current working directory. Per default it uses
+Cwd::cwd but if this doesn't work on your system for some reason,
+alternatives can be configured according to the following table:
+
+    cwd         Cwd::cwd
+    getcwd      Cwd::getcwd
+    fastcwd     Cwd::fastcwd
+    getdcwd     Cwd::getdcwd
+    backtickcwd external command cwd
+
+Preferred method for determining the current working directory?
+
+=item halt_on_failure
+
+Normally, CPAN.pm continues processing the full list of targets and
+dependencies, even if one of them fails.  However, you can specify
+that CPAN should halt after the first failure.  (Note that optional
+recommended or suggested modules that fail will not cause a halt.)
+
+Do you want to halt on failure (yes/no)?
+
+=item histfile
+
+If you have one of the readline packages (Term::ReadLine::Perl,
+Term::ReadLine::Gnu, possibly others) installed, the interactive CPAN
+shell will have history support. The next two questions deal with the
+filename of the history file and with its size. If you do not want to
+set this variable, please hit SPACE ENTER to the following question.
+
+File to save your history?
+
+=item histsize
+
+Number of lines to save?
+
+=item inactivity_timeout
+
+Sometimes you may wish to leave the processes run by CPAN alone
+without caring about them. Because the Makefile.PL or the Build.PL
+sometimes contains question you're expected to answer, you can set a
+timer that will kill a 'perl Makefile.PL' process after the specified
+time in seconds.
+
+If you set this value to 0, these processes will wait forever. This is
+the default and recommended setting.
+
+Timeout for inactivity during {Makefile,Build}.PL?
+
+=item index_expire
+
+The CPAN indexes are usually rebuilt once or twice per hour, but the
+typical CPAN mirror mirrors only once or twice per day. Depending on
+the quality of your mirror and your desire to be on the bleeding edge,
+you may want to set the following value to more or less than one day
+(which is the default). It determines after how many days CPAN.pm
+downloads new indexes.
+
+Let the index expire after how many days?
+
+=item inhibit_startup_message
+
+When the CPAN shell is started it normally displays a greeting message
+that contains the running version and the status of readline support.
+
+Do you want to turn this message off?
+
+=item keep_source_where
+
+Unless you are accessing the CPAN on your filesystem via a file: URL,
+CPAN.pm needs to keep the source files it downloads somewhere. Please
+supply a directory where the downloaded files are to be kept.
+
+Download target directory?
+
+=item load_module_verbosity
+
+When CPAN.pm loads a module it needs for some optional feature, it
+usually reports about module name and version. Choose 'v' to get this
+message, 'none' to suppress it.
+
+Verbosity level for loading modules (none or v)?
+
+=item makepl_arg
+
+Every Makefile.PL is run by perl in a separate process. Likewise we
+run 'make' and 'make install' in separate processes. If you have
+any parameters (e.g. PREFIX, UNINST or the like) you want to
+pass to the calls, please specify them here.
+
+If you don't understand this question, just press ENTER.
+
+Typical frequently used settings:
+
+    PREFIX=~/perl    # non-root users (please see manual for more hints)
+
+Parameters for the 'perl Makefile.PL' command?
+
+=item make_arg
+
+Parameters for the 'make' command? Typical frequently used setting:
+
+    -j3              # dual processor system (on GNU make)
+
+Your choice:
+
+=item make_install_arg
+
+Parameters for the 'make install' command?
+Typical frequently used setting:
+
+    UNINST=1         # to always uninstall potentially conflicting files
+                     # (but do NOT use with local::lib or INSTALL_BASE)
+
+Your choice:
+
+=item make_install_make_command
+
+Do you want to use a different make command for 'make install'?
+Cautious people will probably prefer:
+
+    su root -c make
+ or
+    sudo make
+ or
+    /path1/to/sudo -u admin_account /path2/to/make
+
+or some such. Your choice:
+
+=item mbuildpl_arg
+
+A Build.PL is run by perl in a separate process. Likewise we run
+'./Build' and './Build install' in separate processes. If you have any
+parameters you want to pass to the calls, please specify them here.
+
+Typical frequently used settings:
+
+    --install_base /home/xxx             # different installation directory
+
+Parameters for the 'perl Build.PL' command?
+
+=item mbuild_arg
+
+Parameters for the './Build' command? Setting might be:
+
+    --extra_linker_flags -L/usr/foo/lib  # non-standard library location
+
+Your choice:
+
+=item mbuild_install_arg
+
+Parameters for the './Build install' command? Typical frequently used
+setting:
+
+    --uninst 1       # uninstall conflicting files
+                     # (but do NOT use with local::lib or INSTALL_BASE)
+
+Your choice:
+
+=item mbuild_install_build_command
+
+Do you want to use a different command for './Build install'? Sudo
+users will probably prefer:
+
+    su root -c ./Build
+ or
+    sudo ./Build
+ or
+    /path1/to/sudo -u admin_account ./Build
+
+or some such. Your choice:
+
+=item pager
+
+What is your favorite pager program?
+
+=item prefer_installer
+
+When you have Module::Build installed and a module comes with both a
+Makefile.PL and a Build.PL, which shall have precedence?
+
+The main two standard installer modules are the old and well
+established ExtUtils::MakeMaker (for short: EUMM) which uses the
+Makefile.PL. And the next generation installer Module::Build (MB)
+which works with the Build.PL (and often comes with a Makefile.PL
+too). If a module comes only with one of the two we will use that one
+but if both are supplied then a decision must be made between EUMM and
+MB. See also http://rt.cpan.org/Ticket/Display.html?id=29235 for a
+discussion about the right default.
+
+Or, as a third option you can choose RAND which will make a random
+decision (something regular CPAN testers will enjoy).
+
+In case you can choose between running a Makefile.PL or a Build.PL,
+which installer would you prefer (EUMM or MB or RAND)?
+
+=item prefs_dir
+
+CPAN.pm can store customized build environments based on regular
+expressions for distribution names. These are YAML files where the
+default options for CPAN.pm and the environment can be overridden and
+dialog sequences can be stored that can later be executed by an
+Expect.pm object. The CPAN.pm distribution comes with some prefab YAML
+files that cover sample distributions that can be used as blueprints
+to store your own prefs. Please check out the distroprefs/ directory of
+the CPAN.pm distribution to get a quick start into the prefs system.
+
+Directory where to store default options/environment/dialogs for
+building modules that need some customization?
+
+=item prerequisites_policy
+
+The CPAN module can detect when a module which you are trying to build
+depends on prerequisites. If this happens, it can build the
+prerequisites for you automatically ('follow'), ask you for
+confirmation ('ask'), or just ignore them ('ignore').  Choosing
+'follow' also sets PERL_AUTOINSTALL and PERL_EXTUTILS_AUTOINSTALL for
+"--defaultdeps" if not already set.
+
+Please set your policy to one of the three values.
+
+Policy on building prerequisites (follow, ask or ignore)?
+
+=item randomize_urllist
+
+CPAN.pm can introduce some randomness when using hosts for download
+that are configured in the urllist parameter. Enter a numeric value
+between 0 and 1 to indicate how often you want to let CPAN.pm try a
+random host from the urllist. A value of one specifies to always use a
+random host as the first try. A value of zero means no randomness at
+all. Anything in between specifies how often, on average, a random
+host should be tried first.
+
+Randomize parameter
+
+=item recommends_policy
+
+(Experimental feature!) Some CPAN modules recommend additional, optional dependencies.  These should
+generally be installed except in resource constrained environments.  When this
+policy is true, recommended modules will be included with required modules.
+
+Include recommended modules?
+
+=item scan_cache
+
+By default, each time the CPAN module is started, cache scanning is
+performed to keep the cache size in sync ('atstart'). Alternatively,
+scanning and cleanup can happen when CPAN exits ('atexit'). To prevent
+any cache cleanup, answer 'never'.
+
+Perform cache scanning ('atstart', 'atexit' or 'never')?
+
+=item shell
+
+What is your favorite shell?
+
+=item show_unparsable_versions
+
+During the 'r' command CPAN.pm finds modules without version number.
+When the command finishes, it prints a report about this. If you
+want this report to be very verbose, say yes to the following
+variable.
+
+Show all individual modules that have no $VERSION?
+
+=item show_upload_date
+
+The 'd' and the 'm' command normally only show you information they
+have in their in-memory database and thus will never connect to the
+internet. If you set the 'show_upload_date' variable to true, 'm' and
+'d' will additionally show you the upload date of the module or
+distribution. Per default this feature is off because it may require a
+net connection to get at the upload date.
+
+Always try to show upload date with 'd' and 'm' command (yes/no)?
+
+=item show_zero_versions
+
+During the 'r' command CPAN.pm finds modules with a version number of
+zero. When the command finishes, it prints a report about this. If you
+want this report to be very verbose, say yes to the following
+variable.
+
+Show all individual modules that have a $VERSION of zero?
+
+=item suggests_policy
+
+(Experimental feature!) Some CPAN modules suggest additional, optional dependencies.  These 'suggest'
+dependencies provide enhanced operation.  When this policy is true, suggested
+modules will be included with required modules.
+
+Include suggested modules?
+
+=item tar_verbosity
+
+When CPAN.pm uses the tar command, which switch for the verbosity
+shall be used? Choose 'none' for quiet operation, 'v' for file
+name listing, 'vv' for full listing.
+
+Tar command verbosity level (none or v or vv)?
+
+=item term_is_latin
+
+The next option deals with the charset (a.k.a. character set) your
+terminal supports. In general, CPAN is English speaking territory, so
+the charset does not matter much but some CPAN have names that are
+outside the ASCII range. If your terminal supports UTF-8, you should
+say no to the next question. If it expects ISO-8859-1 (also known as
+LATIN1) then you should say yes. If it supports neither, your answer
+does not matter because you will not be able to read the names of some
+authors anyway. If you answer no, names will be output in UTF-8.
+
+Your terminal expects ISO-8859-1 (yes/no)?
+
+=item term_ornaments
+
+When using Term::ReadLine, you can turn ornaments on so that your
+input stands out against the output from CPAN.pm.
+
+Do you want to turn ornaments on?
+
+=item test_report
+
+The goal of the CPAN Testers project (http://testers.cpan.org/) is to
+test as many CPAN packages as possible on as many platforms as
+possible.  This provides valuable feedback to module authors and
+potential users to identify bugs or platform compatibility issues and
+improves the overall quality and value of CPAN.
+
+One way you can contribute is to send test results for each module
+that you install.  If you install the CPAN::Reporter module, you have
+the option to automatically generate and deliver test reports to CPAN
+Testers whenever you run tests on a CPAN package.
+
+See the CPAN::Reporter documentation for additional details and
+configuration settings.  If your firewall blocks outgoing traffic,
+you may need to configure CPAN::Reporter before sending reports.
+
+Generate test reports if CPAN::Reporter is installed (yes/no)?
+
+=item perl5lib_verbosity
+
+When CPAN.pm extends @INC via PERL5LIB, it prints a list of
+directories added (or a summary of how many directories are
+added).  Choose 'v' to get this message, 'none' to suppress it.
+
+Verbosity level for PERL5LIB changes (none or v)?
+
+=item prefer_external_tar
+
+Per default all untar operations are done with the perl module
+Archive::Tar; by setting this variable to true the external tar
+command is used if available; on Unix this is usually preferred
+because they have a reliable and fast gnutar implementation.
+
+Use the external tar program instead of Archive::Tar?
+
+=item trust_test_report_history
+
+When a distribution has already been tested by CPAN::Reporter on
+this machine, CPAN can skip the test phase and just rely on the
+test report history instead.
+
+Note that this will not apply to distributions that failed tests
+because of missing dependencies.  Also, tests can be run
+regardless of the history using "force".
+
+Do you want to rely on the test report history (yes/no)?
+
+=item urllist_ping_external
+
+When automatic selection of the nearest cpan mirrors is performed,
+turn on the use of the external ping via Net::Ping::External. This is
+recommended in the case the local network has a transparent proxy.
+
+Do you want to use the external ping command when autoselecting
+mirrors?
+
+=item urllist_ping_verbose
+
+When automatic selection of the nearest cpan mirrors is performed,
+this option can be used to turn on verbosity during the selection
+process.
+
+Do you want to see verbosity turned on when autoselecting mirrors?
+
+=item use_prompt_default
+
+When this is true, CPAN will set PERL_MM_USE_DEFAULT to a true
+value.  This causes ExtUtils::MakeMaker (and compatible) prompts
+to use default values instead of stopping to prompt you to answer
+questions. It also sets NONINTERACTIVE_TESTING to a true value to
+signal more generally that distributions should not try to
+interact with you.
+
+Do you want to use prompt defaults (yes/no)?
+
+=item use_sqlite
+
+CPAN::SQLite is a layer between the index files that are downloaded
+from the CPAN and CPAN.pm that speeds up metadata queries and reduces
+memory consumption of CPAN.pm considerably.
+
+Use CPAN::SQLite if available? (yes/no)?
+
+=item version_timeout
+
+This timeout prevents CPAN from hanging when trying to parse a
+pathologically coded $VERSION from a module.
+
+The default is 15 seconds.  If you set this value to 0, no timeout
+will occur, but this is not recommended.
+
+Timeout for parsing module versions?
+
+=item yaml_load_code
+
+Both YAML.pm and YAML::Syck are capable of deserialising code. As this
+requires a string eval, which might be a security risk, you can use
+this option to enable or disable the deserialisation of code via
+CPAN::DeferredCode. (Note: This does not work under perl 5.6)
+
+Do you want to enable code deserialisation (yes/no)?
+
+=item yaml_module
+
+At the time of this writing (2009-03) there are three YAML
+implementations working: YAML, YAML::Syck, and YAML::XS. The latter
+two are faster but need a C compiler installed on your system. There
+may be more alternative YAML conforming modules. When I tried two
+other players, YAML::Tiny and YAML::Perl, they seemed not powerful
+enough to work with CPAN.pm. This may have changed in the meantime.
+
+Which YAML implementation would you prefer?

+=head1 NAME
+
+CPAN::Kwalify - Interface between CPAN.pm and Kwalify.pm
+
+=head1 SYNOPSIS
+
+  use CPAN::Kwalify;
+  validate($schema_name, $data, $file, $doc);
+
+=head1 DESCRIPTION
+
+=over
+
+=item _validate($schema_name, $data, $file, $doc)
+
+$schema_name is the name of a supported schema. Currently only
+C<distroprefs> is supported. $data is the data to be validated. $file
+is the absolute path to the file the data are coming from. $doc is the
+index of the document within $doc that is to be validated. The last
+two arguments are only there for better error reporting.
+
+Relies on being called from within CPAN.pm.
+
+Dies if something fails. Does not return anything useful.
+
+=item yaml($schema_name)
+
+Returns the YAML text of that schema. Dies if something fails.

+C<best_mirrors> checks for the best mirrors based on the list of

+C<how_many>. In list context, it returns up to C<how_many> mirrors.
+In scalar context, it returns the single best mirror.
+
+Arguments
+
+    how_many      - the number of mirrors to return. Default: 1
+    callback      - a callback for find_best_continents
+    verbose       - true or false on all the whining and moaning. Default: false
+    continents    - an array ref of the continents to check
+    external_ping - if true, use external ping via Net::Ping::External. Default: false
+
+If you don't specify the continents, C<best_mirrors> calls
+C<find_best_continents> to get the list of continents to check.
+
+If you don't have L<Net::Ping> v2.13 or later, needed for timings,
+this returns the default mirror.
+
+C<external_ping> should be set and then C<Net::Ping::External> needs
+to be installed, if the local network has a transparent proxy.

+
+C<find_best_continents> goes through each continent and pings C<N>
+random mirrors on that continent. It then orders the continents by
+ascending median ping time. In list context, it returns the ordered list
+of continent. In scalar context, it returns the same list as an
+anonymous array.
+
+Arguments:
+
+    n        - the number of hosts to ping for each continent. Default: 3
+    seen     - a hashref of cached hostname ping times
+    verbose  - true or false for noisy or quiet. Default: false
+    callback - a subroutine to run after each ping.
+    ping_cache_limit - how long, in seconds, to reuse previous ping times.
+        Default: 1 day
+
+The C<seen> hash has hostnames as keys and anonymous arrays as values.
+The anonymous array is a triplet of a C<CPAN::Mirrored::By> object, a
+ping time, and the epoch time for the measurement.
+
+The callback subroutine gets the C<CPAN::Mirrored::By> object, the ping
+time, and measurement time (the same things in the C<seen> hashref) as
+arguments. C<find_best_continents> doesn't care what the callback does
+and ignores the return value.
+
+With a low value for C<N>, a single mirror might skew the results enough
+to choose a worse continent. If you have that problem, try a larger
+value.

+=head1 NAME
+
+CPAN::Plugin::Specfile - Proof of concept implementation of a trivial CPAN::Plugin
+
+=head1 SYNOPSIS
+
+  # once in the cpan shell
+  o conf plugin_list push CPAN::Plugin::Specfile
+
+  # make permanent
+  o conf commit
+
+  # any time in the cpan shell to write a spec file
+  test Acme::Meta
+
+  # disable
+  # if it is the last in plugin_list:
+  o conf plugin_list pop
+  # otherwise, determine the index to splice:
+  o conf plugin_list
+  # and then use splice, e.g. to splice position 3:
+  o conf plugin_list splice 3 1
+
+=head1 DESCRIPTION
+
+Implemented as a post-test hook, this plugin writes a specfile after
+every successful test run. The content is also written to the
+terminal.
+
+As a side effect, the timestamps of the written specfiles reflect the
+linear order of all dependencies.
+
+B<WARNING:> This code is just a small demo how to use the plugin
+system of the CPAN shell, not a full fledged spec file writer. Do not
+expect new features in this plugin.
+
+=head2 OPTIONS
+
+The target directory to store the spec files in can be set using C<dir>
+as in
+
+  o conf plugin_list push CPAN::Plugin::Specfile=dir,/tmp/specfiles-000042
+
+The default directory for this is the
+C<plugins/CPAN::Plugin::Specfile> directory in the I<cpan_home>
+directory.

+# One use of the queue is to determine if we should or shouldn't
+# announce the availability of a new CPAN module
+
+# Now we try to use it for dependency tracking. For that to happen
+# we need to draw a dependency tree and do the leaves first. This can
+# easily be reached by running CPAN.pm recursively, but we don't want
+# to waste memory and run into deep recursion. So what we can do is
+# this:
+
+# CPAN::Queue is the package where the queue is maintained. Dependencies
+# often have high priority and must be brought to the head of the queue,
+# possibly by jumping the queue if they are already there. My first code
+# attempt tried to be extremely correct. Whenever a module needed
+# immediate treatment, I either unshifted it to the front of the queue,
+# or, if it was already in the queue, I spliced and let it bypass the
+# others. This became a too correct model that made it impossible to put
+# an item more than once into the queue. Why would you need that? Well,
+# you need temporary duplicates as the manager of the queue is a loop
+# that
+#
+#  (1) looks at the first item in the queue without shifting it off
+#
+#  (2) cares for the item
+#
+#  (3) removes the item from the queue, *even if its agenda failed and
+#      even if the item isn't the first in the queue anymore* (that way
+#      protecting against never ending queues)
+#
+# So if an item has prerequisites, the installation fails now, but we
+# want to retry later. That's easy if we have it twice in the queue.
+#
+# I also expect insane dependency situations where an item gets more
+# than two lives in the queue. Simplest example is triggered by 'install
+# Foo Foo Foo'. People make this kind of mistakes and I don't want to
+# get in the way. I wanted the queue manager to be a dumb servant, not
+# one that knows everything.
+#
+# Who would I tell in this model that the user wants to be asked before
+# processing? I can't attach that information to the module object,
+# because not modules are installed but distributions. So I'd have to
+# tell the distribution object that it should ask the user before
+# processing. Where would the question be triggered then? Most probably
+# in CPAN::Distribution::rematein.

+=head1 NAME
+
+MLDBM - store multi-level Perl hash structure in single level tied hash
+
+=head1 SYNOPSIS
+
+    use MLDBM;				# this gets the default, SDBM
+    #use MLDBM qw(DB_File FreezeThaw);	# use FreezeThaw for serializing
+    #use MLDBM qw(DB_File Storable);	# use Storable for serializing
+
+    $dbm = tie %o, 'MLDBM' [..other DBM args..] or die $!;
+
+=head1 DESCRIPTION
+
+This module can serve as a transparent interface to any TIEHASH package
+that is required to store arbitrary perl data, including nested references.
+Thus, this module can be used for storing references and other arbitrary data
+within DBM databases.
+
+It works by serializing the references in the hash into a single string. In the
+underlying TIEHASH package (usually a DBM database), it is this string that
+gets stored.  When the value is fetched again, the string is deserialized to
+reconstruct the data structure into memory.
+
+For historical and practical reasons, it requires the B<Data::Dumper> package,
+available at any CPAN site. B<Data::Dumper> gives you really nice-looking dumps of
+your data structures, in case you wish to look at them on the screen, and
+it was the only serializing engine before version 2.00.  However, as of version
+2.00, you can use any of B<Data::Dumper>, B<FreezeThaw> or B<Storable> to
+perform the underlying serialization, as hinted at by the L<SYNOPSIS> overview
+above.  Using B<Storable> is usually much faster than the other methods.
+
+See the L<BUGS> section for important limitations.
+
+=head2 Changing the Defaults
+
+B<MLDBM> relies on an underlying TIEHASH implementation (usually a
+DBM package), and an underlying serialization package.  The respective
+defaults are B<SDBM_File> and B<Data::Dumper>.  Both of these defaults
+can be changed.  Changing the B<SDBM_File> default is strongly recommended.
+See L<WARNINGS> below.
+
+Three serialization wrappers are currently supported: B<Data::Dumper>,
+B<Storable>, and B<FreezeThaw>.  Additional serializers can be
+supported by writing a wrapper that implements the interface required by
+B<MLDBM::Serializer>.  See the supported wrappers and the B<MLDBM::Serializer>
+source for details.
+
+In the following, I<$OBJ> stands for the tied object, as in:
+
+	$obj = tie %o, ....
+	$obj = tied %o;
+
+=over 4
+
+=item $MLDBM::UseDB	I<or>	I<$OBJ>->UseDB(I<[TIEDOBJECT]>)
+
+The global C<$MLDBM::UseDB> can be set to default to something other than
+C<SDBM_File>, in case you have a more efficient DBM, or if you want to use
+this with some other TIEHASH implementation.  Alternatively, you can specify
+the name of the package at C<use> time, as the first "parameter".
+Nested module names can be specified as "Foo::Bar".
+
+The corresponding method call returns the underlying TIEHASH object when
+called without arguments.  It can be called with any object that
+implements Perl's TIEHASH interface, to set that value.
+
+=item $MLDBM::Serializer	I<or>	I<$OBJ>->Serializer(I<[SZROBJECT]>)
+
+The global C<$MLDBM::Serializer> can be set to the name of the serializing
+package to be used. Currently can be set to one of C<Data::Dumper>,
+C<Storable>, or C<FreezeThaw>. Defaults to C<Data::Dumper>.  Alternatively,
+you can specify the name of the serializer package at C<use> time, as the
+second "parameter".
+
+The corresponding method call returns the underlying MLDBM serializer object
+when called without arguments.  It can be called with an object that
+implements the MLDBM serializer interface, to set that value.
+
+=back
+
+=head2 Controlling Serializer Properties
+
+These methods are meant to supply an interface to the properties of the
+underlying serializer used.  Do B<not> call or set them without
+understanding the consequences in full.  The defaults are usually sensible.
+
+Not all of these necessarily apply to all the supplied serializers, so we
+specify when to apply them.  Failure to respect this will usually lead to
+an exception.
+
+=over 4
+
+=item $MLDBM::DumpMeth	I<or>  I<$OBJ>->DumpMeth(I<[METHNAME]>)
+
+If the serializer provides alternative serialization methods, this
+can be used to set them.
+
+With B<Data::Dumper> (which offers a pure Perl and an XS verion
+of its serializing routine), this is set to C<Dumpxs> by default if that
+is supported in your installation.  Otherwise, defaults to the slower
+C<Dump> method.
+
+With B<Storable>, a value of C<portable> requests that serialization be
+architecture neutral, i.e. the deserialization can later occur on another
+platform. Of course, this only makes sense if your database files are
+themselves architecture neutral.  By default, native format is used for
+greater serializing speed in B<Storable>.  Both B<Data::Dumper> and
+B<FreezeThaw> are always architecture neutral.
+
+B<FreezeThaw> does not honor this attribute.
+
+=item $MLDBM::Key  I<or>  I<$OBJ>->Key(I<[KEYSTRING]>)
+
+If the serializer only deals with part of the data (perhaps because
+the TIEHASH object can natively store some types of data), it may need
+a unique key string to recognize the data it handles.  This can be used
+to set that string.  Best left alone.
+
+Defaults to the magic string used to recognize MLDBM data. It is a six
+character wide, unique string. This is best left alone, unless you know
+what you are doing. 
+
+B<Storable> and B<FreezeThaw> do not honor this attribute.
+
+=item $MLDBM::RemoveTaint  I<or>  I<$OBJ>->RemoveTaint(I<[BOOL]>)
+
+If the serializer can optionally untaint any retrieved data subject to
+taint checks in Perl, this can be used to request that feature.  Data
+that comes from external sources (like disk-files) must always be
+viewed with caution, so use this only when you are sure that that is
+not an issue.
+
+B<Data::Dumper> uses C<eval()> to deserialize and is therefore subject to
+taint checks.  Can be set to a true value to make the B<Data::Dumper>
+serializer untaint the data retrieved. It is not enabled by default.
+Use with care.
+
+B<Storable> and B<FreezeThaw> do not honor this attribute.

+
+=head1 EXAMPLES
+
+Here is a simple example.  Note that does not depend upon the underlying
+serializing package--most real life examples should not, usually.
+
+    use MLDBM;				# this gets SDBM and Data::Dumper
+    #use MLDBM qw(SDBM_File Storable);	# SDBM and Storable
+    use Fcntl;				# to get 'em constants
+
+    $dbm = tie %o, 'MLDBM', 'testmldbm', O_CREAT|O_RDWR, 0640 or die $!;
+
+    $c = [\ 'c'];
+    $b = {};
+    $a = [1, $b, $c];
+    $b->{a} = $a;
+    $b->{b} = $a->[1];
+    $b->{c} = $a->[2];
+    @o{qw(a b c)} = ($a, $b, $c);
+
+    #
+    # to see what was stored
+    #
+    use Data::Dumper;
+    print Data::Dumper->Dump([@o{qw(a b c)}], [qw(a b c)]);
+
+    #
+    # to modify data in a substructure
+    #
+    $tmp = $o{a};
+    $tmp->[0] = 'foo';
+    $o{a} = $tmp;
+
+    #
+    # can access the underlying DBM methods transparently
+    #
+    #print $dbm->fd, "\n";		# DB_File method
+
+Here is another small example using Storable, in a portable format:
+
+    use MLDBM qw(DB_File Storable);	# DB_File and Storable
+
+    tie %o, 'MLDBM', 'testmldbm', O_CREAT|O_RDWR, 0640 or die $!;
+
+    (tied %o)->DumpMeth('portable');	# Ask for portable binary
+    $o{'ENV'} = \%ENV;			# Stores the whole environment
+
+
+=head1 BUGS
+
+=over 4
+
+=item 1.
+
+Adding or altering substructures to a hash value is not entirely transparent
+in current perl.  If you want to store a reference or modify an existing
+reference value in the DBM, it must first be retrieved and stored in a
+temporary variable for further modifications.  In particular, something like
+this will NOT work properly:
+
+	$mldb{key}{subkey}[3] = 'stuff';	# won't work
+
+Instead, that must be written as:
+
+	$tmp = $mldb{key};			# retrieve value
+	$tmp->{subkey}[3] = 'stuff';
+	$mldb{key} = $tmp;			# store value
+
+This limitation exists because the perl TIEHASH interface currently has no
+support for multidimensional ties.
+
+=item 2.
+
+The B<Data::Dumper> serializer uses eval().  A lot.  Try the B<Storable>
+serializer, which is generally the most efficient.
+
+=back
+
+=head1 WARNINGS
+
+=over 4
+
+=item 1.
+
+Many DBM implementations have arbitrary limits on the size of records
+that can be stored.  For example, SDBM and many ODBM or NDBM
+implementations have a default limit of 1024 bytes for the size of a
+record.  MLDBM can easily exceed these limits when storing large data
+structures, leading to mysterious failures.  Although SDBM_File is
+used by MLDBM by default, it is not a good choice if you're storing
+large data structures.  Berkeley DB and GDBM both do not have these
+limits, so I recommend using either of those instead.
+
+=item 2.
+
+MLDBM does well with data structures that are not too deep and not
+too wide.  You also need to be careful about how many C<FETCH>es your
+code actually ends up doing.  Meaning, you should get the most mileage
+out of a C<FETCH> by holding on to the highest level value for as long
+as you need it.  Remember that every toplevel access of the tied hash,
+for example C<$mldb{foo}>, translates to a MLDBM C<FETCH()> call.
+
+Too often, people end up writing something like this:
+
+        tie %h, 'MLDBM', ...;
+        for my $k (keys %{$h{something}}) {
+            print $h{something}{$k}[0]{foo}{bar};  # FETCH _every_ time!
+        }
+
+when it should be written this for efficiency:
+
+        tie %h, 'MLDBM', ...;
+        my $root = $h{something};                  # FETCH _once_
+        for my $k (keys %$root) {
+            print $k->[0]{foo}{bar};
+        }
