-# An example of a JSON dialog similar to the one described in CFDialog.py is:
-#
-# {
-#   "location" : "test_grandpa_01",
-#   "rules": [
-#   {
-#     "match" : ["hello","hi"],

-#     "post" : [["hello", "*"]],
-#     "msg" : ["What ?", "Huh ?", "What do you want ?"]
-#   }
-# ]}
-#
-# For detailed descriptions of the match, pre, post, and msg formats, see the
-# ../CFDialog.py script.
-#
-# "match" is a list of keyword strings, and corresponds to what the player says
-# that the dialog will respond to.
-#
-# In the above example, the first rule is applied if the player/character says
-# "hello" or "hi" and if the "hello" flag is set to "0" (default).  When the
-# rule is applied, the "hello" flag is then set to "1".
-#
-# "pre" is a list of preconditions that identifies flags that must be set to a
-# particular value in order to trigger a response if a match is detected.
-#
-# "post" is a list of postconditions that specify flags that are to be set if a
-# response is triggered.
-#
-# All of the rule values are lists, and must be enclosed by square braces, but
-# pre and post are lists of lists, so the nested square braces ([[]]) are
-# required except that using an empty list [] is the best way to indicate when
-# the rule does not need to check preconditions or set postconditions.
-#
-# "msg" defines one or more responses that will be given if the rule triggers.
-# When more than one "msg" value is set up, the NPC randomly selects which one
-# to say each time the rule is applied.
-#
-# A relatively complex example of an npc_dialog.py dialog is given in the Gork
-# treasure room quest.  See ../scorn/kar/gork.msg in particular as it
-# demonstrates how multiple precondition flag values may be exploited to
-# produce non-linear and variable-path conversations that are less likely to
-# frustrate a player.  Refer also to ../scorn/kar/mork.msg to see how more
-# than one dialog can reference the same dialog flags.
+# see http://wiki.metalforge.net/doku.php/user:cavesomething:guide_to_quest_dialogs 
+# for lots of detail on how to use this, and look at examples in test/quest_handling
