example cabal programs

[Isaac Jones]

I have a little collection of programs that use cabal which I use in
my testing script.  It includes:

- a package whose executable depends on the library (not with the
  depend: flag)

- a package with user hooks

- a package where two modules are named Main

- wash2hs

- hunit

- and a handful of random things tested by one packaged called "A"

These should probably go in the examples directory or somehow be
included in CVS.  What's the best way to do this?  The Setup files
should probably be built at least as a sanity check when building
cabal.


peace,
