Guttman, John D. Ramsdell, William M. Farmer, Leonard G. Monk, and Vipin Swarup, of The MITRE Corporation, and Mitchell Wand and Dino Oliva of Northeastern University. This directory contains the ten final reports generated by the members of the project. An overview of the project is presented in the Vlisp Guide.
