+test_ifaddrs
+============
+
+This program prints the addresses and netmasks of all the IPv4 and IPv6
+interfaces on the local machine.  It is useful for testing that this
+functionality works on various platforms.  If "samehost" and "samenet"
+in pg_hba.conf don't seem to work right, run this program to see what
+is happening.
+
+Usage:	test_ifaddrs
