An improved cmd.py for writing multi-command scripts and shells.
cmdln.py is an extension of Python’s default
cmd.py module that
provides “a simple framework for writing line-oriented command
interpreters”. The idea (with both cmd.py and cmdln.py) is to be able
to quickly build multi-sub-command tools (think cvs or svn) and/or
simple interactive shells (think gdb or pdb). Cmdln’s extensions make
it more natural to write sub-commands, integrate optparse for simple
option processing, and make having good command documentation easier.
