cliff -- Command Line Interface Formulation Framework

cliff is a framework for building command line programs. It uses setuptools entry points to provide subcommands, output formatters, and other extensions.

To do

• Should commands have an explicit API for checking whether the user can invoke them?
• example show app
• change API for list app to expect a sequence of dictionaries?
• unicode output for python 2 (incompatible with csv?)
• json formatter(s)
• pprint formatter(s)
• pretty but non-table formatter(s)
• shell script formatter(s)? (properties as variable names)
• create a few example commands that use a sqlite database to show how to manage transactions
• switch setup/teardown functions in app to use some sort of context manager?
