Python Uno Bridge Architecture

[sneha29@gmail.com]

Hi,

I am trying to write a bridge similar to Python- Uno bridge.
I have read from these links about the PyUNO bridge.

http://udk.openoffice.org/python/python-bridge.html

But I haven't found information about the basic achitecture of the
bridge. Eg: the basic requirements of the files, library, specific
directory structure .
Is there any document/tutorial available about the approach taken to
write the bridge?
Also can you tell me about the basic steps required to write a UNO
bridge ?

Thanks,
Sneha
