-=head1 DESCRPITON
+=head1 DESCRIPTION
+
+This module is a CPANPLUS backend that recursively generates Gentoo ebuilds for a given package in the default overlay, updates the manifest, and even emerges it (together with its dependencies) if the user requires it.
+
+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>.
+Existing ebuilds will be searched into the main C<PORTDIR> portage tree and then into the overlays listed in C<PORTDIR_OVERLAY>.
+
+=head1 OPTIONS
+
+You can pass specific options to L<cpan2dist> by using the C<--dist-opts> command-line argument followed by a C<key=value> pair, where C<key> is the option name and C<value> is what it is set to.
+C<--dist-opts> can be used several times.
+
+The valid option C<key>s are :
+
+=over 4
+
+=item *
+
+C<manifest>
+
+A boolean that indicates whether the F<Manifest> file should be generated by running C<ebuild manifest> onto the generated ebuilds.
+
+Defaults to C<yes>.
+
+=item *
+
+C<overlay>
+
+The path of the overlay in which the generated ebuilds will be written.
+
+Defaults to the first overlay listed in C<PORTDIR_OVERLAY> (as returned by C<emerge --info>) or F</usr/local/portage> if this variable is empty.
+
+=item *
+
+C<distdir>
+
+The directory where C<ebuild> expects to find the source tarballs.
+You need write permissions on this directory.
+
+Defaults to the value of C<DISTDIR> (as returned by C<emerge --info>) or F</usr/portage/distfiles> if this variable is empty.
+
+=item *
+
+C<keywords>
+
+The valid C<KEYWORDS> for the generated ebuilds.
+
+Defaults to the value of C<ACCEPT_KEYWORDS> (as returned by C<emerge --info>) or C<'x86'> if this variable is empty.
+
+=item *
+
+C<header>
+
+A chunk of text that is prepended to every ebuild.
+
+Defaults to the generic Gentoo Foundation header.
+
+=item *
+
+C<footer>
+
+A chunk of text that is appended to every ebuild.
-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.
+Defaults to nothing.
-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>.
+=back
+
+L<cpan2dist> itself takes other options, most notably :
+
+=over 4
+
+=item *
+
+C<--buildprereq> generates an ebuild for every dependency, even for those that are already up-to-date.
+Setting this option is recommended.
+
+=item *
+
+C<--force> forcefully regenerates ebuilds even if they already exist.
+
+=item *
+
+C<--install> installs the ebuilds after generating them.
+
+=item *
+
+C<--skiptest> skips tests while building, which speeds up the building process.
+
+=item *
+
+C<--verbose> shows a lot more information.
+
+=back
+
+Please refer to L<cpan2dist> documentation for a complete coverage of its abilities.
=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-0.11.tar.gz
+
+Log in as root and unpack it in e.g. your home directory :
+
+ # cd
+ # tar xzf /tmp/CPANPLUS-Dist-Gentoo-0.11.tar.gz
+ # cd CPANPLUS-Dist-Gentoo-0.11
+
+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
