CPAN::Source fetch, parse, aggregate all CPAN source list for you.

Currently CPAN::Source supports 4 files from CPAN mirror. (00whois.xml, contains cpan author information, 01mailrc.txt contains author emails, 02packages.details.txt contains package information, 03modlist contains distribution status)

CPAN::Source aggregate those data, and information can be easily retrieved.

The distribution info is from CPAN::DistnameInfo.

    my $dist = $source->dist('Moose');
    my $distname = $dist->name;
    my $distvname = $dist->version_name;
    my $version = $dist->version;  # attributes from CPAN::DistnameInfo
    my $meta_data = $dist->fetch_meta();

    $meta_data->{abstract};
    $meta_data->{version};
    $meta_data->{resources}->{bugtracker};
    $meta_data->{resources}->{repository};

    my $readme = $dist->fetch_readme;
    my $changes = $dist->fetch_changes;


    my $pkg = $source->package( 'Moose' );
