I'm just trying to find an easy to create shortcuts on Windows platforms
through Python... it doesn't seem to be a simple matter though.  I've gone
through all the Win32 docs, and found nothing, and have started writing
(with limited success) a C function to do it.
Is there an easy way?  q:]
Here's a quicky demo of both creating and reading a lnk file on windows.
There's no real reason for the wrapper class other than that I'm a
raving lunatic and it's 3am :) ...
