Initially, this file was built as a single unit, which, when completed, weighed in at 5437 lines, 155635 characters. The janitor wanted to keep it as a single file but was convinced by others that this wood not be fair for people trying to access such a beast across a slow line. So, it now is broken up into this "Table of Contents" entry-point file, accompanied by three files comprising the "Notes" sections of the original single file. The original single file is included for completeness:
