I had never used it, so I didn't know about the mechanism. It
seems to me this in interchange.cfg is the only (relatively)
easy way to do it:

GlobalSub hook_to_parser <<EOS
sub {
	sub parse_customtrack {
		my ($var, $name) = @_;
		my $sub = $C->{Sub}->{$name} || $Global::GlobalSub->{$name};
		return $sub || '';
	}
}
EOS

AddDirective  TrackSub customtrack

Then in your catalog.cfg:

Sub <<EOR
sub trackfoo {
   Log("Called trackfoo");
}
EOR

TrackSub trackfoo

The TrackSub can then be the name of a GlobalSub or a Sub -- it needs
to open and write a file or program to do something useful, of course.
