Jatha is a Java library that implements a large subset of Common LISP, including most of the datatypes (e.g. packages, bignums). The API allows access to LISP from Java. Jatha is useful as a fast, embedded LISP language, as a set of dynamically-typed data types, or as a standalone LISP.

Jatha is governed by the Gnu LGPL 3.0 license. Please submit any modifications, bugs, and pull requests to the GitHub site.
