Since the crafty port has been updated, there are inconsistencies
in the opening book ports now. Since the maintainer's email
bounces, I'll volunteer to maintain these as well. The port
has been updated so that it'll actually be seen by crafty,
and has been made accessible for the learning function to
work.
