    Dear Rich,
   database.h gets generated from database.h.in by the file scripts/
makedbh.  The purpose is to automatically generate the bitmask vectors
for tile types.  In the past, changes to the maximum number of tile
types would require hand-editing a slew of macros in the database.h
file.  Mike Godfrey alleviated this somewhat by reducing it to a
couple of #defines, but I decided to get rid of the problem entirely
by generating all the macros based on the TT_MAXTYPES value, using a
script.  I was aware at the time that this would probabaly create
all sorts of bad fallout, though so far I have not had much problem
with it.
   "makedbh" is run from scripts/config, though I suppose technically
it ought to be in a Makefile somewhere.  Just about every file in
the magic source uses database.h, so it has to be run before everything
else.
   The XHelper7 and database/database.h files were *supposed* to be
ignored by CVS, but I can't say I really understand the CVS ignore
stuff.  There doesn't seem to be any way I can specify that these
files be ignored on my end.  I have to send email to Rajit and ask
him to do it at the CVS root.  If you know something I don't, please
clue me in.
						Regards,
						Tim
