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

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

                     74: .Pp
1.64      nicm       75: Each session is persistent and will survive accidental disconnection
1.66      jmc        76: (such as
1.64      nicm       77: .Xr ssh 1
1.67      jmc        78: connection timeout) or intentional detaching (with the

                     81: .Nm

                     89: .Em client
                     90: and all sessions are managed by a single
                     91: .Em server .
                     92: The server and each client are separate processes which communicate through a
                     93: socket in
                     94: .Pa /tmp .
1.65      nicm       95: .Pp
