Python does things I don't understand with paths on Windows, but they
usually turn out right.

 72     def setBuilddir(self, builddir):
 73         assert self.parent
 74         self.builddir = builddir
 75         self.basedir = os.path.join(self.bot.basedir, self.builddir)
 76         if not os.path.isdir(self.basedir):
 77             os.makedirs(self.basedir)

it's using os.path.join, which is the right way.  I'm not sure why
Python chooses to use a / there instead of \.
