argparse 1.0.0
==============
* Some support for ``choices`` argument in ``parser$add_argument``.  Thanks Christopher Small for report/request.

* Some support for ``formatter_class`` argument in ``ArgumentParser``.  Thanks Costas Bouyioukos for report/request.

* Package now looks for Python binaries with ``findpython::find_python_cmd``
  which is a little bit more robust than the previous ``argparse::find_python_cmd``.

* If ``interactive() == TRUE`` then ``parse_args`` will no longer ``quit(status=1)`` after printing a help message
  but will instead throw an error.  ``argparse`` will continue to ``quit(status=1)`` after printing a help message
  for non-interactive Rscripts.


argparse 0.5.3
==============

* Fix bug in parser$add_argument for case when we specify a default vector
  instead of scalar.  Thanks Martin Diehl for bug report.

* ``find_python_cmd`` will now also look for a ``python2.7`` binary.

* Website moved to https://github.com/trevorld/argparse
