=head1 SYNOPSIS

    use Selenium::Remote::Driver;
    
    my $driver = new Selenium::Remote::Driver;
    $driver->get("http://www.google.com");
    print $driver->get_title();
    $driver->quit();

=head1 DESCRIPTION

Selenium is a test tool that allows you to write
automated web application UI tests in any programming language against
any HTTP website using any mainstream JavaScript-enabled browser. This module is
an implementation of the Perl Bindings (client) for the Remote driver that
Selenium provides. You can find bindings for other languages at this location:

L<http://code.google.com/p/selenium/>

This module sends commands directly to the Server using simple HTTP requests.
Using this module together with the Selenium Server, you can automatically
control any supported browser.

To use this module, you need to have already downloaded and started
the Selenium Server.  (The Selenium Server is a Java application.)
