+Description:
+This script is used to make random greetings (or any text you
+want) appear over the head of a NPC when they perceive a player
+and when they are clicked on.
+
+It is called from within a converstation file you create. You
+can use it with 10 lines, 4 lines, or whatever, just change
+the constant "N" at the top of the script, and call this script
+in the text appears field of each line.
+
+You can also include a dialogue as detailed below
+
+The How-To is at the bottom

+How-To:
+
+Create the conversation file for the NPCs:
+
+ In the toolset, go over to conversations at the left, right
+ click, and select new. In this new conversation, add a bunch of
+ nodes right at the top. These are what the NPC will randomly say.
+ Don't put any PC responses for them.
+
+ In the "Text Appears When" box of each node, call this script
+ (062_farmer_say).
+
+ Save the conversation file as generic_farmer (or some such).
+
+To add a dialogue:
+
+ If you want the NPC to also have a normal dilogue, start it
+ after the last random node. DO NOT call this script in that
+ node or the NPC will say the entire dialogue.
+
+ In this script, change the iHasDialogue constant at the top
+ to TRUE.
+
+Enable the NPCs:
+
+ To get your NPC to talk, you need to change two things.
+
+ 1) Use the generic_farmer file as their converstaion.
+
+ 2) In their Scripts section set the On Spawn field to
+    062_farmer_spawn.
+
+ Now all your farmers have something to say when they see a player!
+
+
+Other things you should think about:
+
+Other Sets of NPCs:
+ You might have farmers, hunters, ranchers and so on. You will
+ want to create different conversation files for these groups.
+ Unless all your conversation files are the same node length,
+ you'll need to save farmer_say as "hunter_say" (for example)
+ with a different N (node number). You can still use
+ famer_spawn with the new file, our you can create rename it
+ NPC_GenTalk_spwn file and use it on all of them.
+
+Perception:
+ This script works like clockwork, as long as the NPC isn't moving.
+ As soon as you have them walking waypoints,  they only 'see' you
+ about 1/3 of the time you think they should. Maybe its supposed to
+ be this way?
+
+ BTW - the OnPercieve event doesn't always work like you think it
+ should. If you start the game anywhere near the NPC, you have to
+ leave their perception (like go behind a building) and come back
+ to get it to fire.
+
+The walk waypoint bug:
+ If you do have them walking around, don't forget about the walk
+ waypoints bug that makes NPCs stand still if you interrupt them
+ with a conversation. To fix this, go to the "root" node, look in
+ the the "current file" area, (it's onthe far middle-right ) and
+ in the "end conversation script" boxes put "nw_d2_walkways" for
+ both the "normal" and "aboted" boxes.
