WHAT ARE ALL THOSE SYSTEM BOOKS FOR ANYWAY?

Wondering what all of those SBK files are for? There sure seems to be a lot of them.

AUTHORING SYSTEM BOOKS
System Books are used to provide various aspects of the Authoring functionality which are not built into the Core of Book. Authoring System Books are not a part of (and should not be shipped with) the Runtime system. A System Book is just a ToolBook file with an SBK extension. Feel free to open one up and take a peek at the OpenScript code in it. You'll learn lots.
