45 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.
46 You need write permissions on the directory where Gentoo fetches its source files (usually F</usr/portage/distfiles>).
47 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.
49 The generated ebuilds are placed into the C<perl-gcpanp> category.
50 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>.
54 After installing this module, you should append C<perl-gcpanp> to your F</etc/portage/categories> file.
58 This module inherits all the methods from L<CPANPLUS::Dist::Base>.
59 Please refer to its documentation for precise information on what's done at each step.
