Second, credit where credit is due. Much of the information in this tutorial is based on the Ada 9X Reference Manual and the Ada 9X Rationale (and understandably so). Both were developed by the Ada 9X Mapping/Revision Team based at Intermetrics, Inc., sponsored by the Ada Joint Program Office (AJPO) through the Ada 9X project. The Ada 9X reference manual is also available as a set of files from the AJPO. I've intentionally tried to not duplicate any existing on-line Ada tutor.

This tutorial, Lovelace, was developed on my own time (off-hours). Many people have helped to identify errors or other problems with earlier versions of the tutorial. The background images were provided by NCSA. The animated moving arrow is an animated GIF from The Rocket Shop. Many of the images are from Randy's Icon and Image Bazaar. My thanks to all.
