  * New utility: cabal-parse
  This simple command-line utility is intended to enable the easy
  retrieval of information from a .cabal file, e.g. for use in Makefiles
  or shell-scripts.
      Usage: cabal-parse [-slash] fieldname filename
  Where a field of the .cabal file contains a list, cabal-parse ensures
  (for instance) that interspersed commas are removed for simpler
  onward processing.  The optional -slash flag converts dots in module
  names to slashes, to help find source files.

    M ./configure -2 +8
