+
+The 'changeip' protocol is used by DNS services offered by changeip.com.
+
+Configuration variables applicable to the 'changeip' protocol are:
+  protocol=changeip            ##
+  server=fqdn.of.service       ## defaults to nic.changeip.com
+  login=service-login          ## login name and password registered with the service
+  password=service-password    ##
+  fully.qualified.host         ## the host registered with the service.
+
+Example ${program}.conf file entries:
+  ## single host update
+  protocol=changeip,                                               \\
+  login=my-my-changeip.com-login,                                  \\
+  password=my-changeip.com-password                                \\
