Ahh, the days of wooden computers and iron programmers.   Back then,
compilers were a rare, extra-cost item that you probably wouldn't have
on your mail server and an embedded macro language was an efficient
way to control it.   Still works, but once the macro has been written,
all you have to do is copy it and the m4 processor provides a way to
make customized copies.
