No particular system here.

But I do think I will move Hijack to using incremental diffs rather than the current scheme. This would help me, too.

I'll fire up "smokey" (my very very fast machine) and write a small script to have it generate incremental diffs for all Hijack versions from v1 to present, and then continue with just incremental diffs in the future.

Would that be helpful?

Cheers
