Abstract | PASTE 2005 is the fifth workshop in a series that brings together the program analysis, software tools, and software engineering communities to focus on applications of program analysis techniques in software tools. PASTE 2005 provides a forum for the presentation of exciting research, empirical results, and new directions in areas including (but not limited to): \beginitemize \item program analysis for program understanding, debugging, testing, and reverse engineering \item integration of program analysis into programming environments \item user interfaces for software tools and software visualization \item applications of program slicing, model checking, and other program analysis techniques \item analysis of program execution or program evolution \item integration of, or tradeoffs between, different analysis techniques \item issues in scaling analyses and user interfaces to deal with large systems \enditemize |
