Subject: [PATCH] Stop using modified book.cls

Strictly speaking, using a modified version of a standard class
file should be avoided. Instead, define a class "pfbook" in
pfbook.cls which loads the book class to add an option and
override a couple of definitions.

The addition of the option was originally done in commit
7b8ce4d5ece9 ("Modify book.cls to allow 10.75x8.25-inch PDFs
for hardcover use").

The modification of definitions was originally done in commit
398070c4ae9a ("book.cls: Fix indent after \chapter in twocolumn").

Hi Paul,

It turned out that this is a preferred way to customize an existing
document class.

See: https://tex.stackexchange.com/questions/528/style-class-tutorials
     http://tutex.tug.org/pracjourn/2005-4/hefferon/hefferon.pdf

        Thanks, Akira
