SUMMARY="Automatically build man-pages for your Python project"
DESCRIPTION="Avoid documenting your Python script arguments on two places! This is typically done \
in an argparse.ArgumentParser help configuration (help=, description=, etc.), and also in a \
manually crafted manual page.

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)."
