No processire functions working outside processwire templates directory

I'm trying to do something I thought was really simple but I'm obviously having a brain freeze on it.

I have a form defined using HannaCode. I want the user to be able to fill out the form and have it be submitted to a PHP processing page for emailing results, etc. I had to put that response page in the root directory of the web server for this to work as Processwire won't let you use any PHP file without getting an error. 

The processing page is very simple, just for testing. No matter what I use on that page ($mail, WireMail, $pages->find, etc, etc). I get an error about an undefined variable. 

Am I doing something wrong here? The method for the form is post, the action is the processing PHP page.

This might be the right starting point for your question:

Never used it, but it's possible to use ProcessWire outside of its natural space.
