Bash control of PTZ camera mjpg-streamer

I need a Linux script to control a PTZ camera which is streaming using mjpg-streamer. Streaming is working but I need to get PTZ going. The camera is a QuickCam Orbit AF with pan tilt. Once the job is complete, you must provide a list of all packages required and zip up the final build code so that I can make changes if needed. Show me what you can do and this could lead to a lot more work.
