Here's an extract from 'pstree -c' on a machine running qmail with
daemontools-0.61:
|-svscan-+-supervise---tcpserver
| |-supervise---multilog
| |-supervise---qmail-send-+-qmail-clean
| | |-qmail-lspawn
| | `-qmail-rspawn
| |-supervise---multilog
| |-supervise---tcpserver
| |-supervise---multilog
| |-supervise---tcpserver
| `-supervise---multilog
The tcpservers are listening for smtp, qmtp, pop3.
