# to convert its code during installation under python 3, the
# import fails, but it fails with an error other than ImportError
# (today it's a NameError on StandardError, an exception base
# class). Convert the exception type here so it can be caught in
# packaging.py where we try to determine if we can import and use
# sphinx by importing this module. See bug #1403510 for details.
