    # mimics an already assembled venv, but also contains real Python packages

    # that are not in that layout until they are installed. We can fake it for

    # the latter type by adding the package source directories to the PYTHONPATH

    # directly. For the former group, we only need to add the python-packages

    # directory itself.

    #

    # This could be cleaned up by converting the remaining packages that are in

    # the first category into a typical python source layout (that is, another

    # layer of directory nesting) and automatically adding all subdirectories of

    # python-packages to the PYTHONPATH instead of manually curating this. We

    # can't convert the packages like adb to the other style because doing so

    # would prevent exporting type info from those packages.
