# Taken from python 2.7 and slightly modified for compatibility with
# older versions. Delete when 2.7 is the oldest supported version.
# Modifications:
#  - Use have_discover to raise an error if the user tries to use
#    discovery on an old version and doesn't have discover installed.
#  - If --catch is given check that installHandler is available, as
#    it won't be on old python versions.
#  - print calls have been been made single-source python3 compatibile.
#  - exception handling likewise.
#  - The default help has been changed to USAGE_AS_MAIN and USAGE_FROM_MODULE
#    removed.
#  - A tweak has been added to detect 'python -m *.run' and use a
#    better progName in that case.
#  - self.module is more comprehensively set to None when being invoked from
#    the commandline - __name__ is used as a sentinel value.
#  - --list has been added which can list tests (should be upstreamed).
#  - --load-list has been added which can reduce the tests used (should be
#    upstreamed).
#  - The limitation of using getopt is declared to the user.
