-# This is the new open-adventure dungeon generator. It'll eventually
-# replace the existing dungeon.c It currently outputs a .h and .c pair
-# for C code.
+# This is the open-adventure dungeon generator. It consumes a YAML description of
+# the dungeon and outputs a dungeon.h and dungeon.c pair of C code files.
 #
 # The nontrivial part of this is the compilation of the YAML for
 # movement rules to the travel array that's actually used by
-# playermove().  This program first compiles the YAML to a form
-# identical to the data in section 3 of the old adventure.text file,
-# then a second stage unpacks that data into the travel array.
-#
-# Here are the rules of the intermediate form:
-#
-# Each row of data contains a location number (X), a second
-# location number (Y), and a list of motion numbers (see section 4).
-# each motion represents a verb which will go to Y if currently at X.
-# Y, in turn, is interpreted as follows.  Let M=Y/1000, N=Y mod 1000.
-#		If N<=300	it is the location to go to.
-#		If 300<N<=500	N-300 is used in a computed goto to
-#					a section of special code.
-#		If N>500	message N-500 from section 6 is printed,
-#					and he stays wherever he is.
-# Meanwhile, M specifies the conditions on the motion.
-#		If M=0		it's unconditional.
-#		If 0<M<100	it is done with M% probability.
-#		If M=100	unconditional, but forbidden to dwarves.
-#		If 100<M<=200	he must be carrying object M-100.
-#		If 200<M<=300	must be carrying or in same room as M-200.
-#		If 300<M<=400	game.prop(M % 100) must *not* be 0.
-#		If 400<M<=500	game.prop(M % 100) must *not* be 1.
-#		If 500<M<=600	game.prop(M % 100) must *not* be 2, etc.
-# If the condition (if any) is not met, then the next *different*
-# "destination" value is used (unless it fails to meet *its* conditions,
-# in which case the next is found, etc.).  Typically, the next dest will
-# be for one of the same verbs, so that its only use is as the alternate
-# destination for those verbs.  For instance:
-#		15	110022	29	31	34	35	23	43
-#		15	14	29
-# This says that, from loc 15, any of the verbs 29, 31, etc., will take
-# him to 22 if he's carrying object 10, and otherwise will go to 14.
-#		11	303008	49
-#		11	9	50
-# This says that, from 11, 49 takes him to 8 unless game.prop(3)=0, in which
-# case he goes to 9.  Verb 50 takes him to 9 regardless of game.prop(3).
