Execute OS script at VM startup

Does anyone know of a way to run a OS script (.bat or perl) as soon as a VM is up and running in vCD? Can this be done with Standard vCD or is there another application with in the vCD Suite which can/does do this?

This would be a use case where we are attempting to automatically setup a test environment for developers or testers. Rather than have those users run the script, as soon as the VM is up and running, the script(s) would be run automatically.

Thanks!
