auto launching a script upon login

[Jonathan Hartje]

All,
    I have a YDL 4.0.1 laptop that automatically logs a user in on 
startup. Does anyone know of a config file I can use to launch a set of 
scripts when that user logs in. The machine is slated to be a demo 
machine and thus I want the process to be as simple as possible. I have 
a top level script TOP_LEVEL.sh that I'd like to be run as soon as my 
default user logs in. Any ideas?

Thanks in advance.
Jon
