Documents technical-oriented information that will help developers further extend and exploit DILIGENT’s source code. The document will target two classes of programmers:

• Those who want to reuse the code – Programmers who will use DILIGENT’s libraries to build their own tools, without need to access the source code.
• Those who want to modify/extend the source code – Programmers who will use the platforms source code to enhance it, correct it, adapt it to different environments and applications domains.
