Application to generate CF documentation?

Hi, I am a relative coldfusion newbie.  At my site, we manually code all of our webpages via simple text editor.  Is there a downloadable app out there that will read the through coldfusion/HTML code and generate something like a module calling tree, or generate related application structure documentation?  I've Googled around, but haven't come up with anything yet for coldfusion.

I've never used one of the web development applications (and don't have access to them), but imagine that functionality is automatically built in. I need something stand-alone.  Thanks!
