The thing that got me thinking about it was Happy. Its recently been put in a darcs, and Simon Marlow mentioned to me that they are looking at moving to Cabal for the build system.

The Happy build system now does two things that aren't your standard build actions:

1) It creates module which contains the version string before compilation 2) After compilation it runs CPP on a number of template files with various different "-D" options to genreate the parser templates.

BTW, I recently Cabalised Happy. Get it from the darcs repo: darcs get http://darcs.haskell.org/happy Sorry you duplicated this work, I should have announced something, but I was holding off because it needed a very recent version of Cabal. Cheers, Simon
