Tmux is a "terminal multiplexer", it enables a number of terminals
(or windows) to be accessed and controlled from a single terminal. Tmux is intended to be a simple, modern, BSD-licensed alternative to programs such as GNU screen. Brought in from pkgsrc-wip (PR 40497) where it was maintained by Fulvio Ciriaco.
