32 <para><application>Screen</application> is a terminal multiplexor that
33 runs several separate processes, typically interactive shells, on a single
34 physical character-based terminal. Each virtual terminal emulates a DEC
35 VT100 plus several ANSI X3.64 and ISO 2022 functions and also provides
36 configurable input and output translation, serial port support,
37 configurable logging, multi-user support, and many character encodings,
38 including UTF-8. Screen sessions can be detached and resumed
39 later on a different terminal.</para>
