+// SQ6 advertises a maximum score of 500 but the game is missing two points.
+// The "Official Player's Guide" authorized by Sierra includes a point list
+// that adds up to 500. It claims that three points should be awarded instead
+// of two when untangling the hose and attaching the staple and celery.
+//
+// Since an official point list exists that adds up to the 500 points that the
+// game advertises, we add the two missing points to the inventory actions.
+// Two versions of this patch are necessary because the English PC versions
+// were compiled with line number debugging instructions and the subsequent
+// French, German, and Mac versions weren't.
+//
+// Applies to: All versions
+// Responsible methods: Hookah_Hose:cue, Staple:doVerb, Celery:doVerb
