 =head1 DESCRPITON
 
 This module is a CPANPLUS backend that recursively generates Gentoo ebuilds for a given package in the specified overlay (defaults to F</usr/local/portage>), updates the manifest, and even emerges it (together with its dependencies) if the user requires it.
-You need write permissions on the directory where Gentoo fetches its source files (usually F</usr/portage/distfiles>).
-The valid C<KEYWORDS> for the generated ebuilds are by default those given in C<ACCEPT_KEYWORDS>, but you can specify your own with the C<keywords> dist-option.
 
 The generated ebuilds are placed into the C<perl-gcpanp> category.
 They favour depending on a C<virtual>, on C<perl-core>, C<dev-perl> or C<perl-gcpan> (in that order) rather than C<perl-gcpanp>.
 
+=head1 OPTIONS
+
+You can pass specific options to L<cpan2dist> by using the C<--dist-opts> command-line argument followed by a C<key=value> pair, where C<key> is the option name and C<value> is what it is set to.
+C<--dist-opts> can be used several times.
+
+The valid option C<key>s are :
+
+=over 4
+
+=item *
+
+C<manifest>
+
+A boolean that indicates whether the F<Manifest> file should be generated by running C<ebuild manifest> onto the generated ebuilds.
+
+Defaults to C<yes>.
+
+=item *
+
+C<overlay>
+
+A string formatted as a space-delimited sequence of paths, that lists the different overlays in which existent ebuilds will be looked for.
+
+Defaults to the value of C<PORTDIR_OVERLAY> as returned by C<emerge --info> (usually F</usr/local/portage>).
+
+=item *
+
+C<distdir>
+
+The directory where C<ebuild> expects to find the source tarballs.
+You need write permissions on this directory.
+
+Defaults to the value of C<DISTDIR> as returned by C<emerge --info> (usually F</usr/portage/distfiles>).
+
+=item *
+
+C<keywords>
+
+The valid C<KEYWORDS> for the generated ebuilds.
+
+Defaults to the value of C<ACCEPT_KEYWORDS> as returned by C<emerge --info>.
+
+=item *
+
+C<header>
+
+A chunk of text that is prepended to every ebuild.
+
+Defaults to the generic Gentoo Foundation header.
+
+=item *
+
+C<footer>
+
+A chunk of text that is appended to every ebuild.
+
+Defaults to nothing.
+
+=back
+
+L<cpan2dist> itself takes other options, most notably :
+
+=over 4
+
+=item *
+
+C<--buildprereq> generates an ebuild for every dependency, even for those that are already up-to-date.
+
+=item *
+
+C<--force> forcefully regenerates ebuilds even if they already exist.
+
+=item *
+
+C<--skiptest> skips tests while building, which speeds up the building process.
+
+=item *
+
+C<--verbose> shows a lot more information.
+
+=back
+
+Please refer to L<cpan2dist> documentation for a complete coverage of its abilities.

 =head1 INSTALLATION
 
 Before installing this module, you should append C<perl-gcpanp> to your F</etc/portage/categories> file.
