+
+=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>).
+
+The generated ebuilds are placed into the section C<perl-cpanp>. They favour depending on C<perl-core> or C<dev-perl> rather than C<perl-cpanp>.
+
+=head1 METHODS
+
+All the methods are inherited from L<CPANPLUS::Dist::Base>. Please refer to its perldoc for precise information on what's done at each step.
