<?php

// This is a script which awards credit to users/hosts/teams for WU which have been
// cancelled or have otherwise failed (error_mask != 0).  Credit granted is credit
// claimed, with a hardwired limit of 300 units.  To enable this script change 1 to
// 0 in the testquery() function. The script can be run multiple times without
// doing any harm.  It only grants credit to results which do not (yet) have any
// granted credits.  So it can be run multiple times.
