/**
 *  LiveConnectDrv is an application that drives the testing of the LiveConnect
 *  API test suite.  This driver runs the stand-alone JavaScript engine in C.
 *  To run the LiveConnectTest API suite in Navigator, use XXX an as yet unwritten
 *  driver, which will depend on a generated HTML file to create the test applet.
 *  
 *  <p>
 *  The application requires the following arguments:
 *
 *  <table>
 *  <tr>
 *  <td>    -d
 *  <td>    directory in which LiveConnect test applications are located
 *  </tr>
 *  <tr>
 *  <td>    -s
 *  <td>    list of suites to execute (optional)
 *  </tr>
 *  <tr>
 *  <td>    -o
 *  <td>    directory in which log files will be written
 *  </tr>
 *  <tr>
 *  <td>    -e
 *  <td>    path to the LiveConnect shell executable
 *  </table>
 *
 *  LiveConnectDrv checks the directory, finds the suites in that directory,
 *  and in each suite a list of all the class files in that suite.  For each
 *  class file found, LiveConnectDrv creates a new LiveConnectEnv object,
 *  which runs the test.
 *
 *  <p>
 *
 *  LiveConnectDrv also generates a helper file that is passed to the JavaScript
 *  shell.  The helper file contains statements that allow the shell to run the
 *  test class.
 *
 * 
 *  The contents of the helper file look something like this:  
 *
 *  <pre>
 *  var OUTPUT_DIRECTORY = <i>value of OUTPUT_DIRECTORY</i>
 *  TestClassName = arguments[0];
 *  TestClass = eval( TestClassName );
 *  testclass = new TestClass();
 *  quit();
 *  </pre>
 *
 *  <p> Each test class creates JavaScript TestCase objects through LiveConnect,
 *  and prints results to standard output, just like the JavaScript language
 *  tests do.  Additionally, test logs are created.
 *
 *  <p> The parent test class, LiveConnectTest, contains methods from
 *  com.netscape.javascript.qa.drivers.TestDriver that allow it to write
 *  test results directly to the log files.
