/*! \file
 *  \brief opj_dec_server is a server to decode JPT-stream and communicate locally with JPIP client, which is coded in java.
 *
 *  \section impinst Implementing instructions
 *  Launch opj_dec_server from a terminal in the same machine as JPIP client image viewers. \n
 *   % ./opj_dec_server \n
 *  Keep it alive as long as image viewers are open.\n
 *
 *  To quite the opj_dec_server, send a message "quit" through the telnet.\n
 *   % telnet localhost 5000\n
 *     quit\n
 *  Be sure all image viewers are closed.\n
 *  Cache file in JPT format is stored in the working directly before it quites.
