Help with File Wrappers

I'm not that new to Cocoa, but I can't seem to understand File Wrappers. I noticed them when I opened an RTFD document with "Show Package Contents" from the Finder. I would like to add this to my application (an evolving HTML editor) to save multiple information in double-clickable file.

Anyone know or can point me to some code/help on implementing this? The TextEdit code is a bit much, and the Apple Docs are not much better in terms of implementing this (same with cocoa-dev).

TIA:
Ryan
