- * Yes, this is platform-specific code, and yes, it may rely on classes on certain platforms
- * that are not part of the standard JDK. What we're trying to do, though, is to take something
- * that's frequently desirable but inherently platform-specific -- opening a default browser --
- * and allow programmers (you, for example) to do so without worrying about dropping into native
- * code or doing anything else similarly evil.

- * Anyway, this code is completely in Java and will run on all JDK 1.1-compliant systems without
- * modification or a need for additional libraries. All classes that are required on certain
- * platforms to allow this to run are dynamically loaded at runtime via reflection and, if not
- * found, will not cause this to do anything other than returning an error when opening the
- * browser.

- * There are certain system requirements for this class, as it's running through Runtime.exec(),
- * which is Java's way of making a native system call. Currently, this requires that a Macintosh
- * have a Finder which supports the GURL event, which is true for Mac OS 8.0 and 8.1 systems that
- * have the Internet Scripting AppleScript dictionary installed in the Scripting Additions folder
- * in the Extensions folder (which is installed by default as far as I know under Mac OS 8.0 and
- * 8.1), and for all Mac OS 8.5 and later systems. On Windows, it only runs under Win32 systems
- * (Windows 95, 98, and NT 4.0, as well as later versions of all). On other systems, this drops
- * back from the inherently platform-sensitive concept of a default browser and simply attempts
- * to launch Netscape via a shell command.
