On Linux, trying to run the broker with the ssl module, but forgetting the ssl-cert-db option, yields:
2009-11-24 18:48:18 info SSL plugin not enabled, you must set --qpid-ssl-cert-db to enable it.
1. It's an 'info' message, so is not visible with default logging level set; I added -t to see this.
2. the option that must be set is -
ssl-cert-db, not --qpid-ssl-cert-db (-help reports it correctly)
