cliff is a framework for building command line programs.
It uses entry points to provide subcommands, output formatters, and other extensions. The cliff framework is meant to be used to create multi-level commands such as subversion and git, where the main program handles some basic argument parsing and then invokes a sub-command to do the work. Cliff takes advantage of Python’s ability to load code dynamically to allow the sub-commands of a main program to be implemented, packaged, and distributed separately from the main program. This organization provides a unified view of the command for users, while giving developers the opportunity organize source code in any way they see fit.
Cliff is organized around five objects that are combined to create a useful command line program.
cliff is free and open source software. cliff is being developed under Python 3.
