/* 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.
