  268501 [lholtkamp@mo] Ok, I build ruby myself, and I installed the windows version of SWIG.
  268616 [nobu@ru y- a] Mingw/VC6 and VC8 are not compatible.  Dont' mix them.
  268635 [jan.svitok@g] I guess that's not a problem - SWIG just generates wrapper source
  268767 [lholtkamp@mo] We have that now.

Re: [QUIZ] Twisting a Rope (#137)
267842 [jamesbkoppel] I had a little trouble debugging my solution, and thus I'm turning it in late. I'm also being forced to finish up early, so some of the lesser features sufferred. It implements all three parts (including part 3 subpart d), but I commented out part 3 subpart c, as I was having trouble with it in and earlier version, and did not have time to test whether it works now and debug. Additionally, part 3 subpart a is only kinda implemented, as I didn't have time to make the slices other than (start, length) and range return a rope.
267843 [jamesbkoppel] While append modifies the rope in place, normalize returns a new rope.
