=head1 TITLE
cardinal.pir - A cardinal compiler.
=head2 Description
This is the base file for the cardinal compiler.
This file includes the parsing and grammar rules from
the src/ directory, loads the relevant PGE libraries,
and registers the compiler under the name 'cardinal'.
=head2 Functions
=over 4
=item onload()
