Version 1.6.0 2020-01-20

CafeOBJ is a new generation algebraic specification and programming language. As a direct successor of OBJ, it inherits all its features (flexible mix-fix syntax, powerful typing system with sub-types, and sophisticated module composition system featuring various kinds of imports, parameterised modules, views for instantiating the parameters, module expressions, etc.) but it also implements new paradigms such as rewriting logic and hidden algebra, as well as their combination.

The files in this directory and its sub directories constitute the complete source code for CafeOBJ interpreter.

Please use Github Issues for bug reports, requests, suggestions, etc.

Contact by email is available at `info AT cafeobj DOT org'.

You can down load the binary executable of several platforms from here.

CafeOBJ interpreter uses Common Lisp as a underlying implementation language, and can be built on one of the following platforms:

1. Allegro CL version 8.0 or later
2. SBCL version 1.1.7 or later (http://www.sbcl.org/platform-table.html)
3. CLISP 2.4.9 or later (http://www.clisp.org)

All of these Lisp systems are freely available except Allegro CL. Franz inc. provides free version, please refer to Franz's download site.
