This is a bit of xslt that will take a xml file in the bmk.dtd format
and create a set of html pages that somewhat emulate a column browser.

In order to generate multiple output files from a single xml source
file, I had to use an extension to the xslt language.  This means that
you have to be running xalan to use this template.

If you look over the example file and run the Makefile, you should get a
decent idea of how things work.
