/**
    RhinoDrv is an application for executing JavaScript tests against the
    JavaScript engine implemented in Java.

    <p>

    The application requires two arguments:
    <ul >
    <li >   the full path to the JavaScript test suite directory
    <li >   the full path to a file of shared JavaScript functions that
            should be evaluated by the JavaScript Context before each
            JavaScript test is evaluated.  See the file <b>shell.js</b>
            included in the test suite.
    </ul>

    For example:
    <pre>

    java -classpath /tmp/Rhino/:/tmp/tests COM.netscape.javascript.qa.RhinoDrv 
    /tmp/tests/ecma/ /tmp/tests/ecma/shell.js

    </pre>

    <p>

    Alternatively, you can specify one or many of the suites by using the
    following command-line options:

    <pre >
    -d        Directory in which suites are located
    -s        Names of suites to execute
    -h        Name of helper file
    -p        Optimization level
    -o        Output directory
    -db       Debug level
    -t        Whether or not we're using tinderbox

    </pre>

    For example:
    <pre>

    java -classpath $CLASSPATH com.netscape.javascript.qa.drivers.RhinoDrv -d c:\src\ns\js\tests\ecma\ -s Math Number Function -h shell.js -p 2 -db 0

    </pre>
