Does that mean it starts a new process for every message? The milter
interface chats over a socket to a long-running process so you
don't have to initialize it every time.  MimeDefang also multiplexes
to several slaves that do the scanning work so you don't have to
serialize everything either.

I'm still missing the 'better' part.  And Makefiles have always
been a useful way to automate repetitive tasks - even better
when someone else has written them and embedded the execution
in the program startup script.
