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