python-xpcom 1.8.1.16+nobinonly-0ubuntu1 (amd64 binary) in ubuntu intrepid

 PyXPCOM allows for communication between Python and XPCOM, such that a
 Python application can access XPCOM objects, and XPCOM can access any
 Python class that implements an XPCOM interface.
 With PyXPCOM, a developer can talk to XPCOM or embed Gecko from a
 Python application. PyXPCOM is similar to JavaXPCOM (Java-XPCOM bridge)
 or XPConnect (JavaScript-XPCOM bridge).
 .
 Install this package if you wish to access XPCOM objects from Python, or
 want to use Python components from XPCOM.
