 ** COMMENT Getting linguistic data: names, words, etc.

 ** COMMENT Status ailments
+* NPC Trainers
+** Trainer Pok\eacute{}mon
+# http://hax.iimarck.us/topic/103/
+There are two formats for specifying lists of NPC PPok\eacute{}mon:
+- If all the Pok\eacute{}mon will have the same level, the format is
+- Level (used for all the Pok\eacute{}mon)
+- Any number of Pok\eacute{}mon internal ids.
+- 0x00, to indicate end-of-list.
+- Otherwise, all the Pok\eacute{}mon will have their level
+specified. The format is
+- 0xFF, to indicate that we will be specifying the levels individually[fn::Because 0xFF is a
+forbidden level within the usual gameplay discipline, the game
+makers could safely use 0xFF as a mode indicator.].
+- Any number of alternating Level/Pokemon pairs
+- 0x00, to indicate end-of-list.
