I'll take a cut at doing this but it is obviously very platform
dependent and I'm unfamiliar with platforms other than Windows.
For everything other than Windows, my implementation will be calling
"system" for external utilities based on what I can find on the web.
Oh, and I have no way to test it other than on Windows so could use some
review/testing from others. :)
