Coleman Kane 220ed979de Virgin import (trimmed) of eXpat v2.0.1. Discussed and tested with
sam and phk who are the two consumers of this library. If there is
any other fallout, email me and I will take care of it.

/* This is simple demonstration of how to use expat. This program
reads an XML document from standard input and writes a line with
the name of each element to standard output indenting child
elements by one tab stop more than their parent element.
It must be used with Expat compiled for UTF-8 output.
