generate hg manpage from commands.py docstring
gendoc.py is a script generating a part of the manpage (the commands
help and options) from the docstring in commands.py.
It avoids duplicating the doc between the doc/ directory and the docstrings.
To generate the manpage, 'make doc' will create all the necessary intermediate
files.
