+// On day 9, room 350 outside the cobbler's hut is initialized incorrectly if
+//  disguised as a monk. The entrance to the hut is broken and several minor
+//  messages are incorrect. This is due to the room's script assuming that the
+//  only disguises that day are yeoman and merchant. A monk disguise causes some
+//  tests to pass and others to fail, leaving the room in an inconsistent state.
+//
+// We fix this by changing the yeoman disguise tests in the script to include
+//  the monk disguises. The disguise global is set to 4 for yeoman and 5 or 6
+//  for monk disguises so we patch the tests to be greater than or equals to.
+//
+// Applies to: English PC Floppy, German PC Floppy, English Amiga Floppy
+// Responsible methods: rm350:init, lobbsHut:doVerb, lobbsDoor:doVerb,
+//                      lobbsCover:doVerb, tailorDoor:doVerb
+// Fixes bug #10834
