-<h3>CREDITS</h3>
-    <p>This filter was written through the collaboration of numerous members of the Moodle community. 
-    It was originally based on the missingword format, which included code from Martin Dougiamas and Thomas Robb.
-    Paul Tsuchido Shew wrote this filter in December 2003 incorporating community suggestions for a more robust question format. 
-    The name was conceived as an acronym for  &quot;General Import Format Technology&quot; or something like that, 
-    but it's too long for a simple filter like this, so it just GIFT.</p>
