=head1 NAME

corelist - a commandline frontend to Module::CoreList

=head1 DESCRIPTION

See L<Module::CoreList> for one.

=head1 SYNOPSIS

    corelist -v
    corelist [-a] <ModuleName> | /<ModuleRegex>/ [<ModuleVersion>] ...
    corelist [-v <PerlVersion>] [ <ModuleName> | /<ModuleRegex>/ ] ...

=head1 OPTIONS

=over

=item -a modulename

lists all versions of the given module (or the matching modules, in case you
used a module regexp) in the perls Module::CoreList knows about.

    corelist -a utf8

    utf8 was first released with perl 5.006
      5.006      undef
      5.006001   undef
      5.006002   undef
      5.007003   1.00
      5.008      1.00
      5.008001   1.02
      5.008002   1.02
      5.008003   1.02
      5.008004   1.03
      5.008005   1.04
      5.008006   1.04
      5.008007   1.05
      5.008008   1.06
      5.009      1.02
      5.009001   1.02
      5.009002   1.04
      5.009003   1.06

=item -? or -help

help! help! help! to see more help, try --man.

=item -man

all of the help

=item -v

lists all of the perl release versions we got the CoreList for.

If you pass a version argument (value of C<$]>, like C<5.00503> or C<5.008008>),
you get a list of all the modules and their respective versions.
(If you have the C<version> module, you can also use new-style version numbers,
like C<5.8.8>.)

In module filtering context, it can be used as Perl version filter.

=back

As a special case, if you specify the module name C<Unicode>, you'll get
the version number of the Unicode Character Database bundled with the
requested perl versions.
