  /*! \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.
