=head1 TITLE
matrixy.pir - A Matrixy compiler.
=head2 Description
This is the base file for the Matrixy compiler. Matrixy
is intended to be a clone of MATLAB/Octave for Parrot. See
F<README.POD> for more information about this language.
This file includes the parsing and grammar rules from
the src/ directory, loads the relevant PGE libraries,
and registers the compiler under the name 'Matrixy'.
