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.
The import of tmux is intended to replace window(1) in the not-too-distant
future. For reference, tmux is also present in the base system of FreeBSD
and OpenBSD.
