Tinyfugue is a very popular MUD/MUSH command line client rich in functionality. When using tinyfugue in a graphical environment the only thing it lacks is the peripheral buttons and options that are available to graphical clients. Gtinyfugue aims to embed tinyfugue within a GNOME wrapper that provides the GUI widgets that make tinyfugue easier and more comfortable to use on a day-to-day basis. Embedding tinyfugue rather than using simple telnet gives the gtinyfugue user the advantage of the depth of tinyfugue functionality.
