-/**
- * Utility class to report simple information about the environment.
- * Simplistic reporting about certain classes found in your JVM may
- * help answer some FAQs for simple problems.
- *
- * <p>Usage-command line:
- * <code>
- * java com.sun.org.apache.xalan.internal.xslt.EnvironmentCheck [-out outFile]
- * </code></p>
- *
- * <p>Usage-from program:
- * <code>
- * boolean environmentOK =
- * (new EnvironmentCheck()).checkEnvironment(yourPrintWriter);
- * </code></p>
- *
- * <p>Usage-from stylesheet:
- * <code><pre>
- * <?xml version="1.0"?>
- * <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
- * xmlns:xalan="http://xml.apache.org/xalan"
- * exclude-result-prefixes="xalan">
- * <xsl:output indent="yes"/>
- * <xsl:template match="/">
- * <xsl:copy-of select="xalan:checkEnvironment()"/>
- * </xsl:template>
- * </xsl:stylesheet>
- * </pre></code></p>
- *
- * <p>Xalan users reporting problems are encouraged to use this class
- * to see if there are potential problems with their actual
- * Java environment <b>before</b> reporting a bug. Note that you
- * should both check from the JVM/JRE's command line as well as
- * temporarily calling checkEnvironment() directly from your code,
- * since the classpath may differ (especially for servlets, etc).</p>
- *
- * <p>Also see http://xml.apache.org/xalan-j/faq.html</p>
- *
- * <p>Note: This class is pretty simplistic:
- * results are not necessarily definitive nor will it find all
- * problems related to environment setup. Also, you should avoid
- * calling this in deployed production code, both because it is
- * quite slow and because it forces classes to get loaded.</p>
- *
- * <p>Note: This class explicitly has very limited compile-time
- * dependencies to enable easy compilation and usage even when
- * Xalan, DOM/SAX/JAXP, etc. are not present.</p>
- *
- * <p>Note: for an improved version of this utility, please see
- * the xml-commons' project Which utility which does the same kind
- * of thing but in a much simpler manner.</p>
