+
+The 'njalla' protocol is used by DNS service offered by njal.la.
+
+Configuration variables applicable to the 'njalla' protocol are:
+  protocol=njalla              ##
+  password=service-password    ## Generated password for your dynamic DNS record
+  quietreply=no|yes            ## If yes return empty response on success with status 200 but print errors
+  domain                       ## subdomain to update, use @ for base domain name, * for catch all
+
+Example ${program}.conf file entries:
+  ## single host update
+  protocol=njalla                                             \\
