This package is designed for audio-visual experiments with precise timing, and includes functionality for Eyelink control. This package is designed with the purpose that it be used by LABS^N at the University of Washington. It is not designed for public use.

Therefore, while we welcome bug reports and suggestions from others, NO SUPPORT IS GUARANTEED. Moreover, we can and will change the API as necessary to suit the needs of the lab. Thus, use at your own risk.
