Three htt Processes

The input method server comprises three related programs (htt, htt_server, and htt_xbe) processes running together. One process controls the input method server properties, another controls the population of the input method server (that is, a "watch dog" process), and the third handles input methods of clients.

Usually, you don't need to know the details of these three processes. When htt is started, htt_server and htt_xbe start also.
