Wheat’s BassBook, v.5.0 has left the building. This is the first major update in two years. I completely overhauled the interface. Now each chapter (or, if you choose, the entire book) is assembled on the fly thanks to PHP includes. I stripped out every bit of legacy code. It’s all CSS and solid HTML. A little more sprucing up and it will validate. Surf it and let me know what you think.
