Thanks for taking the time to explain this. It really makes sense now. Once
I get more familiar with ASL/APL and how to build it/use it, I will most
certainly want to help contribute. This is unrelated, but what is the
difference between the Adobe Platform Libraries and the Adobe Source
Libraries? Right now it seems like ASL contains the abstractions, and APL
contains the implementations for those abstractions for each platform.
Correct me if I am wrong.
