[Web-SIG] Daemon server management

[Shannon -jj Behrens]

I usually just write a wrapper that matches whatever OS I'm on.  I.e.
I sacrifice the cross-platform requirement.  Creating a FreeBSD
rc.sh-type script is quite simple.  Perhaps I'm being naive.

As for the pid file, if the user tries to start the server and I see
that it exists, I exit with an error.  If the user tries to stop a
server, and there is no pid file, I exit with an error.  I do it in
shell.

Best Regards,
-jj
