Creating a New Module

Hey guys, I'm looking at this nifty FreeRadius package and I'd like to quickly write a simple XML-RPC module for FreeRadius. I'm looking at the other modules and I'm wondering which one you guys would recommend that I mimic. I just want the simplest, most straightforward module that I could use to just plug in the XML-RPC calls. Any suggestions or perhaps dev documentation that you could point me to? Michael
