+=head1 DESCRIPTION
+
+This B<zone-ls> lists all zones under control of our dnstools suite. The output is ordered by domain name.

+=item B<-e>|B<--expiry>
+
+Order the output by expiry date. The sooner the key expires, the more top the
+domain is listed.

+=back
+
+Additionally the common B<-h>|B<--help>|B<-m>|B<--man> options, which should be
+self explanatory.
