/*! \file
 *  \brief opj_server is a JPIP server program, which supports HTTP connection, JPT-stream, session, channels, and cache model managements.
 *
 *  \section req Requirements
 *    FastCGI development kit (http://www.fastcgi.com).
 *
 *  \section impinst Implementing instructions
 *  Launch opj_server from the server terminal:\n
 *   % spawn-fcgi -f ./opj_server -p 3000 -n
 *
 *  Note: JP2 files are stored in the working directory of opj_server\n
 *  Check README for the JP2 Encoding\n
 *
 *  We tested this software with a virtual server running on the same Linux machine as the clients.
