[Moved from http://code.google.com/p/argparse/issues/detail?id=75]

What steps will reproduce the problem?
1. import argparse
2. print dir(argparse)
3. print argparse.__all__

Compare the output for public methods and attributes from #2 that aren't in #3.

I see the following entries that look like they should be public but aren't in __all__::

'ArgumentTypeError', 'ONE_OR_MORE', 'OPTIONAL', 'PARSER', 'REMAINDER',  'SUPPRESS', 'ZERO_OR_MORE'

I was writing a compat layer to allow unbundling argparse from ipython if it's already installed in the system when I ran across this.  The particular public attribute that was missing there was 'SUPPRESS'
