+# 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.
