# the nix-python way..
# By default python looks in the $prefix/lib/python-$version/site-packages directory
# and reads the .pth files to add the library paths to sys.path.
# Using PYHTONPATH is not enough because it doesn't make python read the .pth files
# telling python where to find additional modules. PYTHONUSERBASE would suffice, but
# it only supports *one* user location. That's why I've added the new env var NIX_PYTHON_SITES
# containing a colon separated list of modules telling python where to look
# for imports and also read the .pth files
# TODO optimize py modules automatically (gentoo has a ebuild function called python_mod_optimize ?)
