+ * up the name from the address. If the resulting name does not contain the
+ * domain name, then the resolve library is broken.
+ *
+ * Warning: It is possible to fool this program into thinking everything is 
+ * alright byt a clever use of /etc/hosts - but this is better than nothing.
+ *
+ * Usage:
+ *   resolve [hostname]
+ *
+ *   When invoked with no arguments, gethostname is used for the local host.
