Note: None of the documentation in this section is designed
specifically for DGD so expect some differences between the listed
sources and how DGD really works!
I've gotten a good start on adapting Ronny Wikh's
LPC Textbook. It was one of the best available sources for
learning LPC. I now believe that my DGD
adaptation is a better way to learn and a better reference,
at least if you're using DGD.
