// | Grabs the names and values of the '$HTTP_*_VARS' variables.
// |---------------------------------------------------------------------------+
// | This library grabs the names and values of the variables sent or posted to
// | a script in the '$HTTP_*_VARS' and new globals arrays defined with
// | php 4.1+ and sets simple globals variables from them.
// | It does the same work for other external variables used in MRBS.
// | USE : This file should be included in all files where external variables
// |       are used, preferably before other included files.
// | :WARNING: thierry_bo 030216: if any new external variable is used,
// |           it must also be added here.
