I built some sample modules with bogus data for JPG to distribute. You can find them here. They aren't as cool as having the full core and dragon modules but they give you a place to start if you want to key in the data by hand.
Note that at the time of the sample build, I didn't have the ability to create custom skills. I've since added this feature to the PHB parser. If you want to add your own skills you need to modify two sections of the code. I posted how to do this over in the 4E group on FUM. I'll see about creating a new sample module with a skill in it for the next release.
