[ANN] argparse 0.7 - Command-line parsing library

[Steven Bethard]

Announcing argparse 0.7
-----------------------

The argparse module is an optparse-inspired command line parser that
improves on optparse by supporting:

* positional arguments
* sub-commands
* required options
* options with a variable number of args
* better usage messages
* a much simpler extension mechanism

and a number of other improvements on the optparse API.

About this release
==================

This release adds support for single-dash long options and combining
single-dash options in a single option string.

Note that the 'outfile' type is still deprecated and will likely be
removed in the next release. Please update your code to use the new
FileType factory.

New in this release
===================

* Single-dash long options (e.g. ``-foo`` or ``-foo-bar``)

* Combining single-dash options (e.g. ``-xy`` is now the same as
  ``-x -y`` when ``-x`` does not take an argument)

Example argparse code
=====================

Here's a simple program that sums its command-line arguments and
writes them to a file::

  parser = argparse.ArgumentParser()
  parser.add_argument('integers', nargs='+', type=int)
  parser.add_argument('--log', default=sys.stdout,
                      type=argparse.FileType('w'))
  args = parser.parse_args()
  args.log.write('%s\n' % sum(args.integers))
  args.log.close()
