+check_pf has been installed to %%PREFIX%%/libexec/nagios.
+
+check_pf needs read permission to the pf(4) pseudo-device, i.e. /dev/pf.
+
+Assuming check_pf will be run by user `nagios', the following will work:
+
+	# chmod 640 /dev/pf
+	# chgrp nagios /dev/pf
+
+To make sure the change persists across reboots, add the following
+to /etc/devfs.conf:
+
+	# nrpe2/nagios needs to be able to read statistics
+	own     pf    root:nagios
+	perm    pf    0640
+	
+Please refer to the online documentation for additional information.

+check_pf is a plugin intended for use with the Nagios network
+monitoring system.  This plugin checks the status of PF, the OpenBSD
+packet filter, and compares the current state count to given or default
+thresholds, returning the result.  It is written in C.
