/**
* A simple command-line XML parsing application.
*
* <p>This class implements a simple command-line XML Parser. It's
* just a little wrapper around the JAXP XMLReader with support for
* catalogs.
* </p>
*
* <p>Usage: xread [options] document.xml</p>
*
* <p>Where:</p>
*
* <dl>
* <dt><code>-c</code> <em>catalogfile</em></dt>
* <dd>Load a particular catalog file.</dd>
* <dt><code>-w</code></dt>
* <dd>Perform a well-formed parse, not a validating parse.</dd>
* <dt><code>-v</code> (the default)</dt>
* <dd>Perform a validating parse.</dd>
* <dt><code>-s</code></dt>
* <dd>Enable W3C XML Schema validation.</dd>
* <dt><code>-n</code></dt>
* <dd>Perform a namespace-ignorant parse.</dd>
* <dt><code>-N</code> (the default)</dt>
* <dd>Perform a namespace-aware parse.</dd>
* <dt><code>-d</code> <em>integer</em></dt>
* <dd>Set the debug level. Warnings are shown if the debug level
* is > 2.</dd>
* <dt><code>-E</code> <em>integer</em></dt>
* <dd>Set the maximum number of errors to display.</dd>
* </dl>
*
* <p>The process ends with error-level 1, if there errors.</p>
