This was a tool to work around a problem in Debian, namely that there was no way to specify gcc flags in a way that would be sure to work for every package that was built. I didn't use it much once I was done with that problem, but a lot of other people did. I kind of wish I'd not written it now, since the problem it worked around is stil there underneath, just paperered over by this kind of tool. Oh well.
This is one of the first peices of software I gave up to let someone else maintain, and I didn't handle it very well, just dumped it. Now I see it's had several maintainers, NMUs, and no updates in three years. Oh well, live and learn.
PS: The name? It sucked. Especially when people started using it to optimise builds for more recent hardware.
