/**
 * Runs a JSP compiler.
 *
 * <p> This task takes the given jsp files and compiles them into java
 * files. It is then up to the user to compile the java files into classes.
 *
 * <p> The task requires the srcdir and destdir attributes to be
 * set. This Task is a MatchingTask, so the files to be compiled can be
 * specified using includes/excludes attributes or nested include/exclude
 * elements. Optional attributes are verbose (set the verbosity level passed
 * to jasper), package (name of the destination package for generated java
 * classes and classpath (the classpath to use when running the jsp
 * compiler).
 * <p> This task supports the nested elements classpath (A Path) and
 * classpathref (A Reference) which can be used in preference to the
 * attribute classpath, if the jsp compiler is not already in the ant
 * classpath.
 *
 * <p><h4>Usage</h4>
 * <pre>
 * &lt;jspc srcdir="${basedir}/src/war"
 *       destdir="${basedir}/gensrc"
 *       package="com.i3sp.jsp"
 *       verbose="9"&gt;
 *   &lt;include name="**\/*.jsp" /&gt;
 * &lt;/jspc&gt;
