+"""
+    Doing this the "right" way by using DIOCNATLOOK on the pf device turns out
+    to be a pain. Apple has made a number of modifications to the data
+    structures returned, and compiling userspace tools to test and work with
+    this turns out to be a pain in the ass. Parsing pfctl output is short,
+    simple, and works.
+
+    Note: Also Tested with FreeBSD 10 pkgng Python 2.7.x.
+    Should work almost exactly as on Mac OS X and except with some changes to
+    the output processing of pfctl (see pf.py).
