=head1 DESCRIPTION
This is certainly not the prettiest way to go about this, but for
now it works for those who might need such a feature.
+=head2 Custom Metaclass alias
+
+This now takes advantage of the Moose 0.19 feature to support
+custom attribute metaclass aliases. This means you can also
+use this as the B<Getopt> alias, like so:
+
+ has 'foo' => (metaclass => 'Getopt', cmd_flag => 'f');
