Coldfusion Google Sitemap Generator

I was looking for a sitemap.xml generator and stubbled across this Google Sitemap Generator Code .  I emailed the gentleman asking if I could put his code on riaforge.com and update it.  He graciously said "Of Course".  I added a pinging function for Yahoo, Google, and Ask.  It submits the sitemap.xml file for their respected search engines.  I also made sure the xml validated properly. I will add better documentation but it should be pretty self explainitory.  Please let me know of any problems because this is untested in other enviroments. UPDATE: This project has been added to RIAForge.org as Google Sitemap XML Generator
