* Added a `:nodefaultconst:` directive, which is similar to the `:nodefault:` directive, but applies only to `store_true`, `store_false`, and `store_const` (e.g., it will hide the "=True" part in the output, since that can be misleading to users).
* Fixed various typos (thanks to users mikeantonacci, brondsem, and tony)
* Format specifiers (e.g., `%(prog)s` and `%(default)s`) are now filled in (if possible) in help sections. If there's a missing keyword, then nothing will be filled in. This was issue 27.
* The package is now a bit more robust to incorrectly spelling module names (39, courtesy of Gabriel Falcão)
* Added support for argparse groups (thanks to Fidel Ramirez)
