tmate - 2.4.0-3+b1 main

tmate provides an instant pairing solution, allowing you to share a terminal
with one or several teammates. Together with a voice call, it's almost like
pairing in person. The terminal sharing works by using SSH connections to
backend servers maintained by tmate upstream developers; teammates need to be
given a randomly-generated token to be able to join a session.
.
tmate is a modified version of tmux, and uses the same configurations such as
keybindings, color schemes etc.
