[IronPython] py to ip

[Rodney Howeedy]

Glauco:
1) I don't recall using tlbimp to try to create an EXPorted COM Interop 
assembly.  I may have my notes incorrect so double check against the 
tutorial.  I used tlbexp to EXPort the COM Interop assembly into a .NET 
2.0 output file.  Here's my command line (note: you can get help from 
tlbexp for additional parameter inputs):
D:\IronPython 2.0\SIEK\9.2_OTAClient>"d:\Program 
Files\Microsoft.NET\SDK\v2.0\Bin\TlbExp.exe" "d:\IronPython 
2.0\SIEK\9.2_OTAClient\OTAClient.dll"

2) I edited my \lib\site.py file and added the complete path to my 
converted output file, "OTAClient.dll", at the path shown on the above 
command line.

3) I then was able to use clr to iPy import my correctly exported COM 
Interop Assembly file:
import clr
clr.AddReferenceToFile("OTAClientInterop.dll")
from OTAClientInterop import *

It has only minimal support for creating such objects (via. clr.AddReferenceToTypeLib), and otherwise relies on the user to create the object using the CLR (Type.GetTypeFromProgID) or other means. You can check if any of the Activator.CreateInstance overloads (http://msdn.microsoft.com/en-us/library/system.activator.createinstance.aspx) support remote COM.
