+
+The 'myaddr' protocol is used by the DNS service offered by myaddr.tools.
+
+Configuration variables applicable to the 'myaddr' protocol are:
+  protocol=myaddr
+  password=key                 ## the private key corresponding to the domain to
+                               ## update
+  name-used-for-logging-only   ## a name (not used by the service; the above key
+                               ## uniquely identifies the domain to update)
+
+Example ${program}.conf file entries:
+  protocol=myaddr, \\
+  password=6bcf18a592bbc85bcee439e1e42def483ff3ef632a84df7ece5ff072f72887c1, \\
