This book contains the final reports of 19 workshops held during the 20th European Conference on Object-Oriented Programming, ECOOP 2006, held in Nantes, France in July 2006. The 19 reports cover the entire range of object technology and related topics, presenting a coherent and highly representative snapshot of the major trends in the field.

Program generation holds the promise of helping to bridge the gap between application-level problem solutions and efficient implementations at the level of today's source programs as written in C or Java. Thus, program generation can substantially contribute to reducing production cost and time-to-market in future software production, while improving the quality and stability of the product.

This book is about domain-specific program generation; it is the outcome of a Dagstuhl seminar on the topic held in March 2003. After an introductory preface by the volume editors, the 18 carefully reviewed revised full papers presented are organized into topical sections on

- surveys of domain-specific programming technologies
- domain-specific programming languages
- tool support for program generation
- domain-specific techniques for program optimization

This book constitutes the refereed proceedings of the ACM SIGPLAN/SIGSOFT Conference on Generative Programming and Component Engineering, GPCE 2002, held in Pittsburgh, PA, USA in October 2002.The 18 revised full papers presented were carefully reviewed and selected from 39 submissions. Among the topics covered are generative programming, meta-programming, program specialization, program analysis, program transformation, domain-specific languages, software architectures, aspect-oriented programming, and component-based systems.
