Clozure CL

Clozure CL (often called CCL) is an open-source software platform that allows developers to run and build programs using the Lisp programming language. It provides an environment where code can be written, tested, and executed efficiently, often used for research, development, or creating complex applications. Clozure CL includes tools like a compiler, interpreter, and debugger, making it a comprehensive system for Lisp programmers. Its design emphasizes performance, portability across operating systems, and extensibility, enabling users to integrate it with other software and develop high-level, dynamic applications.
