I put together this presentation for the 360 Flex conference in San Jose. Thank you to those who attended and filled up the room so I could impress my manager with my supposed popularity.
The presentation contains a basic introduction to modules and how to use them, and an attempt to explain ApplicationDomains which are an important factor in how modules and RSLs (Runtime Shared Libraries) work.

And some sample code is here: Download file
The sample code has build.script files that require a unix shell and show how some of the MXMLC parameters are used. (The usual caveats, disclaimers, and other legal stuff apply).
