=head1 DESCRPITON
-This module is a CPANPLUS backend that recursively generates Gentoo ebuilds for a given package in the specified overlay (defaults to C</usr/local/portage>), update the manifest, and even emerge it (together with its dependencies) if the user requires it. You need write permissions on the directory where Gentoo fetches its source files (usually C</usr/portage/distfiles>).
+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
section C<perl-gcpanp>. They favour depending on C<perl-core> or C<dev-perl> rather than C<perl-gcpanp>.
+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>.
