 The function ``add2virtualenv`` adds the specified directories to the Python path for the active virtualenv. The directory names passed as argument are added to a path file named ``virtualenv_path_extensions.pth`` inside the virtualenv's site-packages directory. If this file does not exist, it will be created first.
