🚀 go-pugleaf

Somewhere I got a neat graphic showing what all the page parameters
do.  In answer to a colleague who thought that altering \headheight would
change the pagination, I decided to do it up in latex.  Since others may
find it useful, I am posting it here.

\kern10pt Note:  The {\tt \!oddsidemargin} (as well as the {\tt
\!evensidemargin}, not shown but having the same effect on even numbered
pages when the {\tt twoside} option is chosen) is inch less than its
actual values, so that a negative distance is required to have less than
a one inch top or left margin.  This is a \LaTeX\ version of a diagram
