[IronPython] C# - IronPython Integration

[boris_aronshtam at vdptech.com]

I am new to IronPython. I am trying to add IronPython scripting  
support to my C# program. I have a number of questions.

Namespaces
----------
Looking at C# examples on WWW, I can see:

using IronPython.Hosting;
using Microsoft.Scripting;
using Microsoft.Scripting.Hosting;

Where can I get documentation on these namespaces?
