-snort.inc
-Must be recoded so that it reads the [snortglobal] [snortglobal][rule] options in conf.xml and makes the files whitelist, snort.sh, snort.conf, and barnyard.conf.
-This is easy, just cut and paste from the old snort.inc. I will work on this.

+<p2>&nbsp;Pfsense <strong>Snort Package</strong> adds network protection from both internal and external threats <br>

+<strong>&nbsp;* Why should I care about my Network Security</strong><br>

+<blockquote>&nbsp;More than 25% of Home PC's are infected with some spyware.</blockquote><br>
