Thanks.  Those are all good references.  
Does anyone have opinions as to where automation of spec updates belong?
I'm wondering why gem2rpm wasn't used for Vit's "fermig" scripts?
It would be nice to have one tool that automated some of the rpm spec changes for rubygems packages.
I hope to get some cycles to work on adding update to an existing spec in gem2rpm in the next week or so, I'll report back anything I come up with.

Thanks.
