The Mesh compiler and runtime make use of the following open-source libraries:
The Mesh compiler uses a parser generated by the Rats! parser generator, part of the xtc eXTensible Compiler project. The generated parser makes use of the Rats runtime library, which is distributed under the LGPL; the rest of the XTC project is distributed under the GPL license, as described on the project's homepage.
Both the Mesh compiler and runtime use Guava, which is distributed under the Apache 2.0 License, as described on the project homepage.
The Mesh compiler uses the Javassist library for bytecode generation. Javassist is distributed under the Apache License (among others).
The Mesh runtime libraries currently include foreign-function bindings to the Processing image rendering and animation Java library, which is distributed under the LGPL, as described on the Processing project's homepage.
The Mesh interactive shell uses the JLine library for terminal emulation. JLine is distributed under the BSD license.
