+# QuestConditionalDrop.py - A script to let items be dropped only if a quest
+# reached a certain step.
+#
+# This script should be called for the 'death' event of a living thing.
+# Each item in inventory will be checked for a 'drop_if_quest' key, which format is:
+# - quest name
+# - a list of steps, either single value (x) or range (x-y)
+# If any matches, then the item will be dropped, else it won't.
+# Items without the 'drop_if_quest' key are not affected.
