ONLogo (OBJECT Networks Logo) is an interpreter engine for Logo written in C++.

In this implementation, every Logo primitive is a C++ function. The interpreter does not depend on the primitives nor the UI, and can be used standalone.

The goal is to implement both an interpreter that could be embedded into C++ programs as a scripting engine, and a stand-alone Logo as much compatible with PC Logo by Harvard Associates (or the newer instance of it, the Terrapin Logo).
