I've been developing my own module for a while. I really appreciate all the information that is provided in Dev wiki.

There is an article that introduces how to add the comment system into the module, but it is only in the case that uses Smarty template. In my module, I avoid using the Smarty templates and generate all HTML codes from a php function instead. Because I am not familiar with Smarty, does anyone could tell me what HTML codes should be added to the module in order to call(display) the built-in comment system? Any suggestion will be greatly appreciated.
