I think the idea is that you could share a syslog.conf between
machines, some of which support the "#!" notation and some of which
don't. For example, we used to share a syslog.conf between FreeBSD
and SunOS machines.

in the paragraph after host specifications, but we've had several
people confused about it, so I suspect the man page is not clear
enough. If you have an idea bout how to make it clearer, let me
