How do I support tab completion in a python CLI program?
I spend a lot of time writing CLI tools in Python, and I would like to support tab-completion in a style similar to Git. For example, subcommands should be tab-completable, options should expand based on the valid choices, and filenames should complete based on the types of files the program supports.
