ISSUES

1. [New comment] Rhino - IronPython - add Leap Motion
http://ironpython.codeplex.com/workitem/35132
User MarkusSchaber has commented on the issue:

"<p>I don't know whether they can do that much, as IronPython simply cannot load cPython extensions directly (the internal data structures are totally different).</p><p>The IronClad project (https://code.google.com/p/ironclad/) tried to solve the gap by adding a wrapper layer, but it seems dormant right now.</p><p>As far as I could see, they also offer support for C#. My guess is that it is a .NET wrapper DLL which offers a "normal" .NET API - this can directly be used by IronPython via clr.AddReference and Import.</p><p>Maybe you could also leverage the websocket interface.</p>"-----------------

User Mjnewsum has commented on the issue:

"<p>I am trying to bring in the C# module like this:</p><p>yourFolder = r"C:\Users\Jake\Desktop\CSetup"<br>import sys<br>import clr<br>import os</p><p>clr.AddReferenceToFileAndPath(os.path.join(yourFolder, "Leap.dll"))</p><p>if yourFolder not in sys.path:<br>    sys.path.append(yourFolder)<br>import Leap</p><p>The Leap.dll file is in the folder, but when I run, it always returns:</p><p>Message: file does not exist: C:\Users\Jake\Desktop\CSetup\LeapCSharp.dll</p><p>Traceback:<br>  line 6, in <module>, "C:\Users\Jake\Desktop\CSetup\CTesting.py"</p><p><br>Is there something I am doing wrong?</p>"-----------------

"IronPython:

Traceback (most recent call last):
