We'll have to wait for Marcus to get back and tell us whether he considers
libGG to be doing things as it should or whether it's due for improvement.
Seems to me to be a waste to not have the more common of these
situations handled automatically by libGG via the configuration file
and instead have everyone getting elbow deep in the loading mechanism
to make their extensions work.

Anyway I'll make sure the HOWTO is adjusted for the state of the
current implementation before release.
