  The terminal is old and crappy: this is not a thing that needs to
  be elaborated on. However, most of the 'modern alternatives', in
  trying to improve on the terminal, improve away most of the advantages
  of a terminal.

  Thule (formerly `GBU`) is a hypothetical UI system that stands
  somewhere between a terminal and window manager, but one that attempts
  to sidestep many of the problems with other computer UI systems. In
  particular, it builds on top of a relatively simple UNIX substrate,
  without trying to reinvent _too_ much elsewhere.

  It consists of a protocol more than an implementation, so that it is
  easy to reimplement elsewhere in many forms.
