    Uninstall.hs - a Haskell uninstaller for Mac OS X
    
    This program is really far too big to be in a single file. However, I
    wanted it to be easily distributable and runnable, and so have kept it all
    together.

Notes

• on lion (and snow leopard i suppose), make sure you are using a 64 bit install of ghc. Also, unless you are suggesting an edit to these directions, please go ask people on the relevant mailing list or wiki for help :)
• Tested on ghc 7.2.2, assumes you have standard developer things installed on mac, like x11 and stuff
• Also tested on GHC 7.0.4 (Haskell Platform) with XCode 4.3.
• These notes were originally brought to you by Carter Schonwald; the “I” probably refers to him. Eric Kow will refer to himself in the third person).

GHC 7.4.x

• gtk2hs 0.12.2 won't build with ghc 7.4.1, but the current darcs repo for gtk2hs does build
