QTR-Quadtone RIP

I have seen reference to a Mini-Tutorial, but I fail to find it in the
files section.  Am I missing something?

I have been reading all the information on QTR I can get my hands
on...and I unfortunately am more confused that ever.  

I am wanting to learn to make QTR curves and profiles from scratch,
but am having difficulty finding a concise cookbook approach.

I have a reasonable grasp of the concepts...and am adept with
IJC/OPM...but I am finding QTR curve creation confusing.

Thanks for pointing me to any files like the Mini Tutorial.
