#######################
# This script exists to help us determine update the library
# versions appropriately. See this page for version details.
#
# http://wiki.sleuthkit.org/index.php?title=Autopsy_3_Module_Versions
#
# The basic idea is that this script uses javadoc/jdiff to
# compare the current state of the source code to the last
# tag and identifies if APIs were removed, added, etc.
#
# When run from the Autopsy build script, this script will:
# - Clone Autopsy and checkout to the previous release tag
# as found in the NEWS.txt file
# - Auto-discover all modules and packages
# - Run jdiff, comparing the current and previous modules
# - Use jdiff's output to determine if each module
# a) has no changes
# b) has backwards compatible changes
# c) has backwards incompatible changes
# - Based off it's compatibility, updates each module's
# a) Major version
# b) Specification version
# c) Implementation version
# - Updates the dependencies on each module depending on the
# updated version numbers
#
# Optionally, when run from the command line, one can provide the
# desired tag to compare the current version to, the directory for
# the current version of Autopsy, and whether to automatically
# update the version numbers and dependencies.

USAGE:
Compares the API of the current Autopsy source code with a previous
tagged version. By default, it will detect the previous tag from
the NEWS file and will not update the versions in the source code.
OPTIONAL FLAGS:
-t --tag Specify a previous tag to compare to.
Otherwise the NEWS file will be used.
-d --dir The output directory for the jdiff JavaDocs. If no
directory is given, the default is jdiff-javadocs/{module}.
-s --source The directory containing Autopsy's source code.
-a --auto Automatically update version numbers (not dry).
-h --help Prints this usage.
