# This patch to djbdns 1.05 modifies the dnscache program to keep a
# counter of cache hits and cache misses.
#
# Two new fields are added to the ``stats'' output line:
# . the fifth number is the number of cache hits
# . the sixth number is the number of cache misses
# e.g.
# @400000003fa92ccc317d70f4 stats 3 1201 1 0 21 49

This patch change djbdns's dnscache program so that it will ignore the
