[AG-TECH] Venue Client Entry simulator for AGTK 2.3

[Andrew Rowley]

Hi,

I have written a short script (see below) that simulates the entry,
heartbeats and exit of a client from an AGTk 2.3 venue server.  I thought it
might be useful to someone out there, such as people who want to use a
dynamic venue without needing an AGTk 2.3 user to be in the venue.  This
script enters the venue with a given URL, and holds the venue open until the
user presses ctrl-c to quit.

I am not sure if this is a good way of doing this but it seems to work...

Andrew :)

Script is below my signature and attached to the e-mail...
