/*! \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.
