 * This script helps reduce the stack frame of an XDebug trace file
 * into a lesser level. Right now there is no way to do this
 * natively with XDebug although there is an open request for the
 * feature here http://bugs.xdebug.org/view.php?id=722
 *
 * You can use this script like:
 *
 * php process-xdebug-trace.php -f /path/to/trace.file -d frame-depth
 *
 * At the moment this is only able to recognize text based trace files
 * with default collect params.
