Look in the docs directory for clamd.pdf and go through chapter 5. It
explains how to talk to the clamd daemon via tcp/unix sockets. Of course
clamd must be running in this case but it vastly reduces the programming
requirements to program a daemon using the lib. MailScanner used/can use the
perl mod for directly handling the scanning but this results in each child
loading the lib and databases, using clamd through sockets does not bring
along this extra overhead.
