/**
 * <code>RMISecurityManager</code> provides an example security manager for
 * use by RMI applications that use downloaded code.  RMI's class loader will
 * not download any classes from remote locations if no security manager has
 * been set.  <code>RMISecurityManager</code> does not apply to applets, which
 * run under the protection of their browser's security manager.
 *
 * <p>To use the <code>RMISecurityManager</code> in your application , add
 * the following statement to your code (it needs to be executed before RMI
 * can download code from remote hosts, so it most likely needs to appear
 * in the <code>main</code> of your application):
 *
 * <pre>
 * System.setSecurityManager(new RMISecurityManager());
 * </pre>
