 *
 * - {@code SELENIUM_BROWSER}: defines the target browser in the form
 *   {@code browser[:version][:platform]}.
 *
 * - {@code SELENIUM_REMOTE_URL}: defines the remote URL for all builder
 *   instances. This environment variable should be set to a fully qualified
 *   URL for a WebDriver server (e.g. http://localhost:4444/wd/hub). This
 *   option always takes precedence over {@code SELENIUM_SERVER_JAR}.
 *
 * - {@code SELENIUM_SERVER_JAR}: defines the path to the
 *   <a href="https://www.selenium.dev/downloads/">
 *   standalone Selenium server</a> jar to use. The server will be started the
 *   first time a WebDriver instance and be killed when the process exits.
 *
 * Suppose you had mytest.js that created WebDriver with
 *
 *     var driver = new webdriver.Builder()
 *         .forBrowser('chrome')
 *         .build();
 *
 * This test could be made to use Firefox on the local machine by running with
 * `SELENIUM_BROWSER=firefox node mytest.js`. Rather than change the code to
 * target Google Chrome on a remote machine, you can simply set the
 * `SELENIUM_BROWSER` and `SELENIUM_REMOTE_URL` environment variables:
 *
 *     SELENIUM_BROWSER=chrome:36:LINUX \
 *     SELENIUM_REMOTE_URL=http://www.example.com:4444/wd/hub \
 *     node mytest.js
 *
 * You could also use a local copy of the standalone Selenium server:

 * In the 3.x releases, the various browser option classes

 *     let ffo = new firefox.Options();
 *     // Configure firefox options...
 *
 *     let caps = new Capabilities();

 *         .withCapabilities(caps)
 *         .build();
 *
 * The options are now subclasses of Capabilities and can be used directly. A
 * direct translation of the above is:
 *
 *     let ffo = new firefox.Options();
 *     // Configure firefox options...
 *
 *     let driver = new Builder()
 *         .withCapabilities(ffo)
 *         .build();

 * You can also set the options for various browsers at once and let the builder
 * choose the correct set at runtime (see Builder docs above):
 *
 *     let ffo = new firefox.Options();
 *     // Configure ...
 *
