License on Doc Code Examples

I've looked around and can't find any information on what copyright 
license, if any, applies to example code in the entrained DotGnu class 
library documentation.  For example, there is some great example code 
for the System.Net.Sockets.Socket class, but I don't know whether I can 
use it or, if so, under what circumstances.  Does anyone know the answer 
to this license issue?
