/**

* <p>A simple, static class to display a URL in the system browser.<br></p>

*

* <p>Under <b>Unix</b> systems, it will open one of the browser set through the

* <b>setBrowserCommand(String)</b>. The argument of this method

* must be a fully qualified command or one of the commands returned

* by <b>getSupportedBrowsers()</b>.<br>By default, the browser is Firefox,

* which is included in the list of supported browsers.<br></p>

*

* <p>Under <b>Windows</b>, this will bring up the default browser under windows,

* usually either Netscape or Microsoft IE.  The default browser is

* determined by the OS so no config is necessary.<br>This has been tested under Windows 95/98/NT/XP.</p>

* <p>Notice that <b>you must include</b> the url type -- either "http://" or  "file://".</p>

*

* <p>Under <b>Mac</b>, the usability of this class is pending of test. So probably it does not work</p>

* Examples:

* BrowserControl.displayURL("http://www.javaworld.com")

* BrowserControl.displayURL("file://c:\\docs\\index.html")

* BrowserContorl.displayURL("file:///user/joe/index.html");
