+/*
+ * Configure a named virtual host in Apache httpd.
+ *
+ * Parameters:
+ *
+ * - urls
+ * Specifies one or more addresses that this virtual host handles, i.e.
+ * which 'Listen' directives apply to it, on the format of URLs, in the
+ * same format as apache::listen does. Listen directives must however
+ * be configured separately; this definition does not do that for you.
+ * This parameter can be either a single URL, or a list of URLs.
+ *
+ * - servernames
+ * Which hostnames in URLs this virtual host applies to. Translates
+ * into 'ServerName' and 'ServerAlias' directives. Defaults to the
+ * hostnames (before resolving) in the 'urls' parameter if not specified.
+ *
+ * - documentroot
+ * The document root for the virtual host. Optional (Apache will by
+ * default inherit this setting from the server-global setting).
+ *
+ * - config
+ * Configuration directives to put inside the virtual host declaration.
+ * A string, or list of strings that will be concatenated with newlines
+ * between them. This will be surrounded by a '<VirtualHost>' container
+ * with 'NameVirtualHost' directives, and 'ServerName', 'ServerAlias'
+ * and optionally 'DocumentRoot' directives inside.
+ *
+ * - ensure
+ * One of 'present' (the default) or 'absent'.
