/* ******************************************** Notes *********************************************
***************************************************************************************************

This is only checking for common operating systems.  Linux and *NIX are checked also even though 
they aren't supported or aren't commonly used.  Checking mobile devices is not currently scripted into this detection, though this check may work for some mobile devices.

I haven't added any mobile platforms, although some could still be identified, but don't count on 
device identification.

This is checking most browsers and versions.  I didn't bother checking for anything below 
Netscape 6.0, mostly because the agent strings are very vague and hard to identify.

If you make any improvements/additions to this script, please share them with me and I will modify 
this and redistribute.
