=head1 NAME
Test::AutoBuild::Stage::CreateRepo - Create an package repository index for package management tools
=head1 SYNOPSIS
  use Test::AutoBuild::Stage::CreateRepo
  my $stage = Test::AutoBuild::Stage::CreateRepo->new(name => "crearerepo",
                                               label => "Create package repository index",
                                               options => {
                                                 directory => "/var/lib/builder/public_html/dist",
                                                 parameters => "-d -s -n",
                                               });
  $stage->run($runtime);
=head1 DESCRIPTION
This module invokes the C<createrepo(8)> command to generate an index of RPM
packages generated during the build. The index enables use of the C<yum(8)>
command to install packages generated by the builder. The C<crearerepo(8)>
command is expected to be found in the C<$PATH>.
=head1 CONFIGURATION
In addition to the standard parameters defined by the L<Test::AutoBuild::Stage>
module, this module accepts two entries in the C<options> parameter:
=over 4
=item directory
The full path to the directory containing RPMs to be indexed. If this option
is not specified, then the C<directories> option must be set.
=item directories
An array of paths to directories containing RPMs to be indexed. If this option
is not specified, then the C<directory> option must be set.
=item parameters
A string of command line arguments to be passed to the C<createrepo> command,
see the C<createrepo(8)> manual page for details of possible values.

=head2 EXAMPLE
  {
    name = createrepo
    label = Update Pacakge Repository
    module = Test::AutoBuild::Stage::CreateRepo
    critical = 0
    options = {
      directory = /var/lib/builder/public_html/dist
      parameters = -d
    }
  }

=cut
package Test::AutoBuild::Stage::CreateRepo;

use warnings;

For each directory defined in the C<options> parameter, this method will
run the C<createrepo> command to generate the index.
