supporter confusion

I've read a lot of great things about the supporter plug-in, about how you can add other plugins or themes to it, etc.

What I have NOT read is any clear concise information on how to make this happen. I have read through as many posts as I could find on the subject but so far I have yet to find one clear set of instruction on how to add plugins AND themes into supporter.

Yes, I know about the examples in supporter and even played around with a couple of single file plugins though didn't actually get them to work.

I see that James, Andrew and Dr. Mike are very active here so I trust this will resolve quickly.

Thanks guys,
