----------------
- We report files that we've added to buildout now so that buildout
automatically cleans them up for us. No more pollution in our
develop-eggs directory!
- Symlinking folders of non-egg distributions that we found in a
system directory turned out to be a bad idea. Some distributions
install files instead of directories (GDAL ends up as ``gdal.py``,
for instance). We now only copy the "egg-info" files, which turns
out to be enough for setuptools to find the distributions.
- Copying (see above) instead of symlinking means it also works on
windows again.
