Background

A previous version of this book was written in 1999 under the title ``How to modify the GNAT Run-Time to experiment with Ada extension'' [MGGM99]. That book was the result of a project to integrate Drago[5] into the GNAT sources. (Drago was the result of my PhD research. It is an Ada extension which facilitates the programming of fault-tolerant and cooperative distributed applications by means of the addition of the groups paradigm into the Ada language).

Although the book was available on the web, no publicity was sent out. Ingenuously we thought that the internet search engines would provide the book to any interested people. Obviously very few people found it, but we thought that the book was not good enough and we stopped our efforts.

During the AdaEurope’2001 conference (Belgium) I presented the book to some colleagues and felt that the book could still be of interest for the Ada community. Therefore, in July 2001 I decide to personally restart the project with the following goals:

I have been working on this book for one year and half. In July 2002 the first Beta version of the book was available in the WEB. In September 2002 I added the GNU Free Documentation License to the book, and I put the full sources on my web site. Now (December 2002) I give you the upgraded version of the book which is now integrated with the GNAT 3.15p sources and has 288 hyper-links to these sources.
