New issue 82 by Arfrever...@gmail.com: argparse 1.2 incompatible with
Python 3.1
http://code.google.com/p/argparse/issues/detail?id=82

argparse 1.1 was compatible with Python 3.1 (all 1485 tests were passing).
argparse 1.2 is incompatible with Python 3.1.

Output of tests of argparse 1.2:
$ PYTHONPATH=. python3.1 test/test_argparse.py
Traceback (most recent call last):
File "test/test_argparse.py", line 13, in <module>
from StringIO import StringIO
ImportError: No module named StringIO

It's not only a bug in test suite. If I copy test_argparse.py from argparse
1.1 and try to run tests against argparse 1.2, then there are 1060 errors.

Thomas, any chance you could take a look at this? The previous releases of
argparse ran on Python 2.3-3.1.

I'll have a look.

Isn't argparse in stdlib since 2.7 (and also in 3.x)?

If so, why do you use the package?

argparse is in stdlib in 2.7 and >=3.2, not 3.1.

Thanks for the patch. I applied a very similar change, but also "fixed" the
python 2.3 testing issue the same way. I changed the version comparison for
consistency reasons.
