The request names cmux, which none of the candidate sources describe; the closest matches are tools for working with the command line and terminal sessions. Sentry's CLI 1 and tmuxp's terminal session management 2 are the strongest fits for a command-line tool, while Urwid 5 and Docopt 7 cover terminal interface and CLI argument work.

A question back: cmux is not described in any of the candidate sources. Do you mean a specific cmux tool, such as a terminal multiplexer or a CLI for a particular platform?
