                     34: .Nm
1.59      jmc        35: is a terminal multiplexer:
                     36: it enables a number of terminals to be created, accessed, and
                     37: controlled from a single screen.
1.67      jmc        38: .Nm
                     39: may be detached from a screen
                     40: and continue running in the background,
                     41: then later reattached.
1.1       nicm       42: .Pp
1.60      nicm       43: When
                     44: .Nm
                     45: is started it creates a new
                     46: .Em session
                     47: with a single
                     48: .Em window
                     49: and displays it on screen.
                     50: A status line at the bottom of the screen
                     51: shows information on the current session
                     52: and is used to enter interactive commands.
                     53: .Pp
                     54: A session is a single collection of

                     56: under the management of
                     57: .Nm .

                     59: windows linked to it.
                     60: A window occupies the entire screen
                     61: and may be split into rectangular panes,
                     62: each of which is a separate pseudo terminal
                     63: (the
                     64: .Xr pty 4
                     65: manual page documents the technical details of pseudo terminals).
                     66: Any number of
                     67: .Nm
                     68: instances may connect to the same session,
                     69: and any number of windows may be present in the same session.
                     70: Once all sessions are killed,

                     73: .Pp
1.64      nicm       74: Each session is persistent and will survive accidental disconnection
1.66      jmc        75: (such as
1.64      nicm       76: .Xr ssh 1
1.67      jmc        77: connection timeout) or intentional detaching (with the

                     80: .Nm

                     89: and all sessions are managed by a single
                     90: .Em server .
                     91: The server and each client are separate processes which communicate through a
