Thu Aug 23 14:29:46 PDT 2007 Duncan Coutts <duncan@haskell.org> * Add a "build-tools:" field to the cabal file format It's the same format as the build-depends, eg: build-tools: cpphs, c2hs >= 0.15 During the configure step we try to configure the listed programs and if a version range is specified then we check that it is satisfied.
