Guis widget server is a Gtk2 widget server. It listens on pipes for
widget requests (in the Python or Ruby (or Slang, etc.) scripting
languages), and emit replies or events in textual lines (e.g. Lispy, XML
or plain token syntax). It is useful for programs (in particular setuid
programs) and scripts that don't or can't link the Gtk2 libraries and
need to delegate the user interface to another process.
