New Grabbing Tool
=================

The new grabbing tool include two parts: the code running in cmucam3
and the software running in PC. You should unzip
"cmucam3.rar" and install it on your CMUcam3 first. And then you should download
and un-rar "cmucam location.rar". You should be able to execute the software by
double clicking on "cmucam location.exe".

The code running in cmucam3 is similiar to the code of cmucam2 project. The soft
in PC is based on Microsoft Visual C++ 6.0. The new tool includes not only the
basic functions in "cmucam frame grabber", but also some new functions, such as
