/**
* <code>JWhich</code> is a utility that takes a Java class name
* and displays the absolute pathname of the class file that would
* be loaded first by the class loader, as prescribed by the
* class path.
* <p>
* Usage is similar to the UNIX <code>which</code> command.
* <p>
* Example uses:
* <p>
* <blockquote>
* To find the absolute pathname of <code>MyClass.class</code>
* not in a package:
* <pre>java JWhich MyClass</pre>
*
* To find the absolute pathname of <code>MyClass.class</code>
* in the <code>my.package</code> package:
* <pre>java JWhich my.package.MyClass</pre>
* </blockquote>
