-/**\r
- * BrowserLauncher is a class that provides one static method, openURL, which opens the default\r
- * web browser for the current user of the system to the given URL. It may support other\r
- * protocols depending on the system -- mailto, ftp, etc. -- but that has not been rigorously\r
- * tested and is not guaranteed to work.\r
- * <p>\r
- * Yes, this is platform-specific code, and yes, it may rely on classes on certain platforms\r
- * that are not part of the standard JDK. What we're trying to do, though, is to take something\r
- * that's frequently desirable but inherently platform-specific -- opening a default browser --\r
- * and allow programmers (you, for example) to do so without worrying about dropping into native\r
- * code or doing anything else similarly evil.\r
- * <p>\r
- * Anyway, this code is completely in Java and will run on all JDK 1.1-compliant systems without\r
- * modification or a need for additional libraries. All classes that are required on certain\r
- * platforms to allow this to run are dynamically loaded at runtime via reflection and, if not\r
- * found, will not cause this to do anything other than returning an error when opening the\r
- * browser.\r
- * <p>\r
- * There are certain system requirements for this class, as it's running through Runtime.exec(),\r
- * which is Java's way of making a native system call. Currently, this requires that a Macintosh\r
- * have a Finder which supports the GURL event, which is true for Mac OS 8.0 and 8.1 systems that\r
- * have the Internet Scripting AppleScript dictionary installed in the Scripting Additions folder\r
- * in the Extensions folder (which is installed by default as far as I know under Mac OS 8.0 and\r
- * 8.1), and for all Mac OS 8.5 and later systems. On Windows, it only runs under Win32 systems\r
- * (Windows 95, 98, and NT 4.0, as well as later versions of all). On other systems, this drops\r
- * back from the inherently platform-sensitive concept of a default browser and simply attempts\r
- * to launch Netscape via a shell command.\r
- * <p>\r
