Beginner's Guide to SleepyHead

SleepyHead is the result of years of work. It is an outstanding, well designed and executed program that runs on Windows, MacOS and Ubuntu. It is also open source. I have downloaded and looked at the source code. It's largely written in C++, which I understand but it's overwhelming. After spending a few days with SleepyHead, I have decided to throw in the towel on Dragon Breath. SleepyHead does pretty much everything I had in mind. I can't say enough good things about it.
