=head1 NAME 

Class::MOP::Module - Module Meta Object

=head1 DESCRIPTION

A module is essentially a L<Class::MOP::Package> with metadata, in our
case the version and authority.

=head1 INHERITANCE

B<Class::MOP::Module> is a subclass of L<Class::MOP::Package>.

=head1 METHODS

=over 4

=item B<< $metamodule->version >>

This is a read-only attribute which returns the C<$VERSION> of the
package, if one exists.

=item B<< $metamodule->authority >>

This is a read-only attribute which returns the C<$AUTHORITY> of the
package, if one exists.

=item B<< $metamodule->identifier >>

This constructs a string which combines the name, version and
authority.

=item B<< Class::MOP::Module->meta >>

This will return a L<Class::MOP::Class> instance for this class.
