+The 'mydns' protocol is used by a free dynamic DNS service offered by www.mydns.jp.
+
+Configuration variables applicable to the 'mydns' protocol are:
+  protocol=mydns               ##
+  server=fqdn.of.service       ## defaults to www.mydns.jp
+  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=mydns
+  login=my-mydns.jp-login
+  password=my-mydns.jp-password
+  myhost.mydns.jp
