Bug 758823 - Don't create egg-info directories when populating virtualenv; r=ted This patch basically bypasses setup.py for pure Python packages. Instead of producing .egg-info directories in the source tree, it merely installs .pth files pointing back to the source directory. As a result, this is less junk in the source tree. The .hgignore and .gitignore entries for egg-info directories have been removed because there should no longer be egg-info directories any more. People should clean up these orphaned directories manually. This can be accomplished by running: $ hg status -u | grep .egg-info | xargs rm -rf $ git ls-files -o '*.egg-info*' | xargs rm -rf
