twin 0.5.1-3ubuntu2 (amd64 binary) in ubuntu intrepid

 Twin is a windowing environment with mouse support, window manager,
 terminal emulator and networked clients, all inside a text display.
  It supports a variety of displays:
  * plain text terminals (any termcap/ncurses compatible terminal,
 Linux console, twin's own terminal emulator);
  * X11, where it can be used as a multi-window xterm;
  * itself (you can display a twin on another twin);
  * twdisplay, a general network-transparent display client, used
 to attach/detach more displays on-the-fly.
