-# Usage: reverse.py <zone_filename>...
-#
-# This demo script will load in all of the zones specified by the
-# filenames on the command line, find all the A RRs in them, and
-# construct a reverse mapping table that maps each IP address used to
-# the list of names mapping to that address.  The table is then sorted
-# nicely and printed.
-#
-# Note!  The zone name is taken from the basename of the filename, so
-# you must use filenames like "/wherever/you/like/dnspython.org" and
-# not something like "/wherever/you/like/foo.db" (unless you're
-# working with the ".db" GTLD, of course :)).
-#
-# If this weren't a demo script, there'd be a way of specifying the
-# origin for each zone instead of constructing it from the filename.
