+ "perl-gcpan" (in that order) rather than "perl-gcpanp". Existing ebuilds
+ will be searched into the main "PORTDIR" portage tree and then into the
+ overlays listed in "PORTDIR_OVERLAY".
+
+OPTIONS
+ You can pass specific options to cpan2dist by using the "--dist-opts"
+ command-line argument followed by a "key=value" pair, where "key" is the
+ option name and "value" is what it is set to. "--dist-opts" can be used
+ several times.
+
+ The valid option "key"s are :
+
+ * "manifest"
+
+ A boolean that indicates whether the Manifest file should be
+ generated by running "ebuild manifest" onto the generated ebuilds.
+
+ Defaults to "yes".
+
+ * "overlay"
+
+ The path of the overlay in which the generated ebuilds will be
+ written.
+
+ Defaults to the first overlay listed in "PORTDIR_OVERLAY" (as
+ returned by "emerge --info") or /usr/local/portage if this variable
+ is empty.
+
+ * "distdir"
+
+ The directory where "ebuild" expects to find the source tarballs.
+ You need write permissions on this directory.
+
+ Defaults to the value of "DISTDIR" (as returned by "emerge --info")
+ or /usr/portage/distfiles if this variable is empty.
+
+ * "keywords"
+
+ The valid "KEYWORDS" for the generated ebuilds.
+
+ Defaults to the value of "ACCEPT_KEYWORDS" (as returned by "emerge
+ --info") or 'x86' if this variable is empty.
+
+ * "header"
+
+ A chunk of text that is prepended to every ebuild.
+
+ Defaults to the generic Gentoo Foundation header.
+
+ * "footer"
+
+ A chunk of text that is appended to every ebuild.
+
+ Defaults to nothing.
+
+ cpan2dist itself takes other options, most notably :
+
+ * "--buildprereq" generates an ebuild for every dependency, even for
+ those that are already up-to-date. Setting this option is
+ recommended.
+
+ * "--force" forcefully regenerates ebuilds even if they already exist.
+
+ * "--install" installs the ebuilds after generating them.
+
+ * "--skiptest" skips tests while building, which speeds up the
+ building process.
+
+ * "--verbose" shows a lot more information.
+
+ Please refer to cpan2dist documentation for a complete coverage of its
+ abilities.
