I added support for extracting feats. I ran a few tests on various issues of Dragon (during which I found more Compendium errors). Then I moved on to Divine Power. Divine power added the extra wrinkle of Feat Powers not to mention a much wider variety of data.
Anyhow the picture shows the results of a run against Divine Power. I still had to make a class and race file but the bulk of the work was done by SSPX.
