42 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.
44 The generated ebuilds are placed into the C<perl-gcpanp> category. They favour depending on C<perl-core>, C<dev-perl> or C<perl-gcpan> (in that order) rather than C<perl-gcpanp>.
48 After installing this module, you should append C<perl-gcpanp> to your F</etc/portage/categories> file.
52 All the methods are inherited from L<CPANPLUS::Dist::Base>. Please refer to its documentation for precise information on what's done at each step.
