The good thing about an ArgumentParser objects is that it actually provides a traversable "tree-like" structure, with all the necessary info needed to automatically generate documentation, for example in a groff typesetting system (manual pages). And this is where this project can help.
There are two supported ways to generate the manual, either script it using the installed command argparse-manpage, or via setup.py build automation (with a slight bonus of automatic manual page installation with setup.py install).
