This file once had a few different printouts.  Now it only has character
sheets.  It has space for a variable to stipulate how many sheets should
be printed - you just echo \setcounter{track}{n} into the file
.count.tex.

The booklet.pdf file needs flipped on the short side of the paper for it
to print properly within other books.  The booklet.pdf file can remain
in landscape mode - it'll print fine on its own when flipped on the long
edge.

The books now keep common makefile commands in config/vars.  A new
command will give pdfs titles according to the first header in the
README file.

They don't like to be compiled without rules or docs. Perhaps
they get lonely.
