tl-ldap-certalias is one tool that has neither a --help nor a -h option. Trying to specify one of those gives a traceback! I believe that all of our tools should have --help and/or -h options, and they shouldn't traceback on unknown options. I think we should write an automatic test for this, and then fix all broken tools.
