This page has some stuff I've done for GURPS
GURPS is the Generic Universal Roleplaying System from Steve Jackson Games.
I have created a data file for GURPS Character Assistant (GCA) 4 from Steve Jackson Games to use Ritual Magic with the 4th edition Basic set. This does not (yet) include the spells and colleges from the Magic book. You can download the file here.
For discussion about GCA check out the GURPS Character Assistant and Vehicle Builder forum at forums.sjgames.comIf you have specific problems with this data file email me at email@example.com. Please do not expect a rapid response. It's likely to be very slow, but I will eventually get around to it.
I also have a conversion program to convert older GCA characters to a format that is viewable on Palm PDAs here.
