 --pid-file=file::
 	Save the process id in 'file'.
 
+--user=user, --group=group::
+	Change daemon's uid and gid before entering the service loop.
+	When only `--user` is given without `--group`, the
+	primary group ID for the user is used.  The values of
+	the option are given to `getpwnam(3)` and `getgrnam(3)`

+Giving these options is an error when used with `--inetd`; use

 <directory>::
 	A directory to add to the whitelist of allowed directories. Unless
 	--strict-paths is specified this will also include subdirectories
