 * \section certi_user_executables CERTI executables
 * CERTI comes with two main executables: RTIA and RTIG.

 * \subsection certi_user_execute
 * If ones want to properly execute an HLA simulation using CERTI one must:
 * (FIXME more detail to come).
 * <ol> 
 *  <li> configure PATH </li>
 *  <li> store .fed (or .xml) FOM file in the search path of the rtig \see certi_FOM_FileSearch</li>
 *  <li> run rtig, \see certi_executable_RTIG </li>
 *  <li> configure HOST/PORT/PROXY, </li>
 *  <li> run federations, rtia is started automatically. </li>
 * </ol>
 * \subsection certi_user_env CERTI environment variables
 * 
 * CERTI uses a set of environment variables which may influence its 
 * execution behavior.
 * <center>
 * <TABLE>
 * <tr>
 * <td><b>Variable</b></td><td><b>Used by</b></td><td><b>Description</b></td>
 * </tr>
 * <tr>
 * <td>CERTI_HOME</td> <td>RTIG</td><td>the CERTI installation base directory.
 *                                      This is used by the RTIG in order
 *                                      to look for FOM files 
 *                                      (see \ref certi_executable_RTIG).</td>
 * </tr>
 * <tr>
 * <td>CERTI_HOST</td> <td>RTIA</td><td>machine on which RTIG is running. 
 *                                      As soon as it starts the RTIA will try to connect 
 *                                      to the RTIG running on CERTI_HOST 
 *                                      (see \ref certi_executable_RTIA).</td>
 * </tr>
 * <tr>
 * <td>CERTI_TCP_PORT</td> <td>RTIG, RTIA</td> <td>TCP port used for RTIA/RTIG communications</td>
 * </tr>
 * <tr>
 * <td>CERTI_UDP_PORT</td> <td>RTIG, RTIA</td> <td>UDP port used for RTIA/RTIG communications</td>
 * </tr>
 * <tr> <td>CERTI_HTTP_PROXY</td> <td>RTIA</td>
 * <td>HTTP proxy address in the format http://host:port.
 * See \ref certi_HTTP_proxy "HTTP tunneling".</td>
 * </tr>
 * <tr> <td>http_proxy</td> <td>RTIA</td>
 * <td>System-wide HTTP proxy address used if CERTI_HTTP_PROXY is not defined.</td>
