[AG-TECH] ANL bridge machine and port info?

[Derek Piper]

	Hi,

	How would I go about running the server on its own? The binary that 
comes with the AGConnector package complains about being run incorrectly 
but doesn't give any useful information. I'm having trouble finding a 
UMTP server that I can run on a central machine. I'm modifying the 
AGConnector python script to have this machine as the default, so people 
should be able to run it without configuring a new server.

	Derek
