Proceedings of the 2009 ACM SIGPLAN workshop on Partial evaluation and program manipulation

It is our great pleasure to welcome you to the ACM SIGPLAN Workshop on Partial Evaluation and Program Manipulation -- PEPM'09. This year's workshop continues its tradition of being the premier forum for presentation of research results and experience reports on leading edge issues of partial evaluation and semantics-based manipulation of programs. The call for papers was based on a broad interpretation of semantics-based program manipulation and continues last years' successful effort to expand the scope of PEPM significantly beyond the traditionally covered areas of partial evaluation and specialization, specially encouraging papers that break new ground, including descriptions of how program/model manipulation tools can be integrated into realistic software development processes, descriptions of robust tools capable of effectively handling realistic applications, and new areas of application such as rapidly evolving systems, distributed and web-based programming including middleware manipulation, model-driven development, and on-the-fly program adaptation driven by run-time or statistical analysis. The call for papers attracted 36 submissions. All submissions were rigorously reviewed by at least three program committee members, with further input from more than 30 external reviewers. The program committee accepted 18 research papers and 2 tool demonstrations. The proceedings also include two invited contributions by Umut Acar and Cristina Cifuentes.
