I need to add some build system stuff for GHC: Makefile, package.conf.in, and
possibly configure.ac. Instead of the fps dependency, there will be a base>=2.0
dependency (ideally we would have conditional dependencies, but Cabal support
for that isn't ready yet).
Since time is short, I plan to integrate regex-base, regex-compat and
regex-posix today, then I'll pull over any changes you make. I'll do this by
replicating your trl-stable darcs repo and morphing it into each of the smaller
repos, that way we don't lose history, and the repo isn't large to begin with.

A lot of the documentation seems to refer to JRegex - while this is useful for
someone moving from one to the other, it won't mean much to someone trying to
grok the new regex stuff in GHC 6.6. Any chance of having some more basic docs?
