python3-cliff 4.0.0-0ubuntu1 (amd64 binary) in ubuntu lunar

 Cliff is a framework for building command line programs. It uses plugins to
 define sub-commands, 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.
 .
 This package provides the Python 3.x module.
