# Note: dcreverse is not built by default.  It does the opposite
# of dctile.  It takes a bitmap with lots of tiles, specifies regions,
# and cuts them out into smaller pieces.  It's useful only for when somebody
# updates the tiles directly and then doesn't give you the source files.
# Not that I'm bitter.

# of a low priority though, as tiles will be rebuilt infrequently.
