title: Smarty Template includes a file that doesn't exist in filesystem, yet still produces content?
body: <p>I have a .tpl that includes another that is responsible for producing a block of code I want to edit. I found out where it was by commenting out the {include...} that produces the content. However, when I hunt for the .tpl file on the filesystem, it does not exist. So where is it really stored?</p>
  
  <p>i.e. {include file="user/content.tpl"}
  (not located in filesystem)</p>
  
  <p>Is there  some hard-coded address for this in some other file? Is there a conditional if: if file doesn't exist, use this one instead?</p>
