Added ability to use the "pod" tag in a texxml file to tell the help
system to grab stuff out of a perl module and format it as .tex. The
good news is this is a good deal more powerful then I would have hoped;
code to select various parts of the perldoc was already written; see
"man Pod::Select". (Cool!)
Also updated the formatting; this code is some of the first code I wrote
and it did not conform to LON-CAPA style.
