+// = DESCRIPTION
+//     This is a simple test of <ACE::get_ip_interfaces>.  This call
+//     retrieves the IP addresses assigned to the host by
+//     interrogating the kernel.  Network applications typically
+//     assume gethostbyname(uname()) will work, but this is just a
+//     convention. It is also problematic if the resolver code
+//     (DNS/NIS+...) is misconfigured. This happens more than
+//     programmers realize. It is better to find out by asking the
+//     kernel for local address assignments. This API is similar to
+//     what netstat -ni or ifconfig -a produces on UNIX or ipconfig on
+//     Windows NT. In fact, it was by reverse engineering these tools
+//     that this api was created.
