 Screen is a powerful program that allows your terminal session to have
 multiple windows and retain context between multiple logins. This
 version of screen is configured with a task bar at the bottom of the
 window that shows system status, pending updates, and which window you
 are currently viewing.

 screen is configured to remap the escape prefix from ctrl-A to ctrl-G.
