+		PROGRAM() does not need any special privileges.
+
+		If started as root (EUID == 0) this option must be given at the
+		command line (not in the configuration file) so that PROGRAM()
+		can drop the root privileges right after parsing the command line
+		options, but before parsing the configuration file. In this case,
+		real/effective/saved UID are all set to the UID of <username>. As
+		the configuration file is read afterwards, those options that have
+		a default value depending on the UID (e.g. the directory for the
+		configuration file) are computed by using the uid of <username>. This
+		option has no effect if PROGRAM() is started as a non-root user (i.e.
+		EUID != 0).
