=head1 SYNOPSIS
=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.
+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 INSTALLATION
-After installing this module, you should append C<perl-gcpanp> to your F</etc/portage/categories> file.
+Before installing this module, you should append C<perl-gcpanp> to your F</etc/portage/categories> file.
+
+You have two ways for installing this module :
+
+=over 4
+
+=item *
+
+Use the perl overlay located at L<http://git.overlays.gentoo.org/gitweb/?p=proj/perl-overlay.git>.
+It contains an ebuild for L<CPANPLUS::Dist::Gentoo> which will most likely be up-to-date given the reactivity of Gentoo's Perl herd.
+
+=item *
+
+Bootstrap an ebuild for L<CPANPLUS::Dist::Gentoo> using itself.
+
+First, make sure your system C<perl> is C<5.10> or greater, so that the L<CPANPLUS> toolchain is available.
+
+ $ perl -v
+ This is perl 5, version 12, subversion 2 (v5.12.2)...
+
+C<perl> C<5.12> is the current stable Perl version in Gentoo.
+If you still have C<perl> C<5.8.x>, you can upgrade it by running the following commands as root :
+
+ # emerge -tv ">=dev-lang/perl-5.10"
+ # perl-cleaner --all
+
+Then, fetch the L<CPANPLUS::Dist::Gentoo> tarball :
+
+ $ cd /tmp
+ $ wget http://search.cpan.org/CPAN/authors/id/V/VP/VPIT/CPANPLUS-Dist-Gentoo-0.10.tar.gz
+
+Log in as root and unpack it in e.g. your home directory :
+
+ # cd
+ # tar xzf /tmp/CPANPLUS-Dist-Gentoo-0.10.tar.gz
+ # cd CPANPLUS-Dist-Gentoo-0.10
+
+Bootstrap L<CPANPLUS::Dist::Gentoo> using the bundled shell script C<g-cpanp> :
+
+ # perl Makefile.PL
+ # make
+ # PERL5LIB=blib/lib samples/g-cpanp CPANPLUS::Dist::Gentoo
+
+Finally, emerge the C<CPANPLUS-Dist-Gentoo> ebuild you've just generated :
+
+ # emerge -tv CPANPLUS-Dist-Gentoo
+
