The htt package is a sample implementation of the internet/intranet input method (iiim) framework. iiim is the next generation input method framework under development. compared to old solutions like xim, iiim provides benefits like platform independence; multilingual, unicode support; distributed architecture; and efficient, lightweight client and server.

the xim backend module is part of the iiim x window system client framework. xbe is a small bridge server that translates the iiim protocol to the old xim protocol, so that xim clients like mozilla and gtk+ programs can use the input methods provided by an iiim server.
