+cdist-type__pf_ruleset(7)
+==================================
+Jake Guffey <jake.guffey--@--eprotex.com>
+
+
+NAME
+----
+cdist-type__pf_ruleset - Copy a pf(4) ruleset to $__target_host
+
+
+DESCRIPTION
+-----------
+This type is used on *BSD systems to manage the pf firewall's ruleset.
+
+
+REQUIRED PARAMETERS
+-------------------
+state::
+   Either "absent" (no ruleset at all) or "present"
+
+
+OPTIONAL PARAMETERS
+-------------------
+source::
+   If supplied, use to define the ruleset to load onto the $__target_host for pf(4).
+   Note that this type is almost useless without a ruleset defined, but it's technically not
+   needed, e.g. for the case of disabling the firewall temporarily.
+
+EXAMPLES
+--------
+
+--------------------------------------------------------------------------------
+# Remove the current ruleset in place
+__pf_ruleset --state absent
+
+# Enable the firewall with the ruleset defined in $__manifest/files/pf.conf
+__pf_ruleset --state present --source $__manifest/files/pf.conf
+
