cabal

I would like my cabalised program to have a --version switch.

I would like it to report the same version as is present in the .cabal file.

If I have to update the version number separately in my Haskell source code as well as in the .cabal file, I will eventually get them out of sync.

So, how can my program, while being compiled under cabal, get its version number from the .cabal file?
