Hi,
+* --pidfile=PATH
+
+Write the process id (PID) to the given file PATH. This is mostly
+useful if the backend daemonize/fork itself.
Is there any reason to daemonize itself?
If not: shoud we disallow it and drop the --pidfile switch?
If yes: should we add a --daemonize switch then to control whenever the
process daemonizes itself?
Otherwise the conventions look good to me.
cheers,
Gerd
