=head1 NAME

Metabase::Resource::perl::commit - class for Metabase resources about perl commits

=head1 VERSION

version 0.017

=head1 SYNOPSIS

  my $resource = Metabase::Resource->new(
    'perl:///commit/8c576062',
  );

  my $resource_meta = $resource->metadata;
  my $typemap       = $resource->metadata_types;
  my $url = $self->full_url;

=head1 DESCRIPTION

Generates resource metadata for resources of the scheme 'perl:///commit'.

  my $resource = Metabase::Resource->new(
    'perl:///commit/8c576062',
  );

For the example above, the resource metadata structure would contain the
following elements:

  scheme       => perl
  type         => commit
  sha1         => 8c576062

=head1 METHODS

=head2 full_url

  my $url = $self->full_url($host);

Returns an ordinary HTTP URL to the resource.  If C<$host> is not
given, it defaults to the official master Perl repository at
L<http://perl5.git.perl.org>.
