//OS detection is relatively straightforward, as long as you know the ins and outs. Explorer says Windows, while Netscape says Win, so always detect Windows by searching for Win. Not surprisingly, if the string Mac is available the OS is Macintosh. If you find X11 this means the computer runs X-Windows for Unix, if in addition the string Linux is found the OS is Linux.

// Browser detect in order to ascertain OS
//   this is not ideal but it will help
//   to display the Flash better in most cases
// The only problem being that many modern browsers
//   allow the useragent to be changed to avoid
//   these very workarounds.
