=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.
Defaults to nothing.
=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
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-0.12.tar.gz
Log in as root and unpack it in e.g. your home directory :
# cd
# tar xzf /tmp/CPANPLUS-Dist-Gentoo-0.12.tar.gz
# cd CPANPLUS-Dist-Gentoo-0.12
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
=back
=head1 METHODS
This module inherits all the methods from L<CPANPLUS::Dist::Base>.
Please refer to its documentation for precise information on what's done at each step.
