... as it is planned for executables, right? I used the Cabal test
mechanism once, but it was not portable between different versions of
Cabal. Thus I added an Executable stanza to the Cabal file and run the
resulting test binary by darcs. Of course I think that in the long run
tests should be managed by Cabal somehow in order to let Hackage check
uploaded packages against their test suites or in order to let compiler
implementors check whether new compiler versions break existing code.
