python This Python module aims at providing almost automatically shell completion for any Python program that already uses the optparse module. This module aims at placing the shell completion routine and the option parsing code in a single location: in the program itself. The logic is that since a program already knows about its options, and in Python we have a standard module to specify them programmatically since Python-2.3 (optparse), the program itself is in the best position to suggest completions for an incomplete command-line to a shell that invokes it.
