Although I'm a TeX/LaTeX neophyte, I've taken on a rather ambitious project of updating Differential Calculus with SAGE. As I go along I'm using the existing
tex document to teach myself what each piece of code does. And right at the start, I'm stumped.
Line 5 of the master file reads
but I can't find any place where this option is documented. There are only blank lines and comments above this, and googling for "latex documentclass runningheads" hasn't resulted in any useful information.
As a side question, I suppose that I'm also wondering if there's any definitive place to go for documentation on all of the LaTeX macros and their options.
