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

Notational tricks:

 * iff a merger has mergers as both children, break them up with a newline
 * use L/R for "left" and "right" repo
 * use capital letters for the hunk patches
 * normalise m(R L) to m(L R)
 * normalise m(m(...) X) to m(X m(...))
 * normalise m(m(R..) m(L..)) to m(m(L..) m(R..))
 * normalise m(.. t) to m(t ..)
 * save repeated trees as tN
