Chez Scheme is an efficient and reliable implementation of Scheme based on an incremental optimizing compiler that produces efficient code and does so quickly. Petite Chez Scheme is a complete Scheme system that is fully compatible with Chez Scheme but uses a fast interpreter in place of the compiler. It was conceived as a run-time environment for compiled Chez Scheme applications, but is also useful as a stand-alone Scheme system. Programs written for Chez Scheme run unchanged in Petite Chez Scheme, as long as they do not depend specifically on the compiler, albeit not as quickly and without the debugging information generated by the compiler. In fact, Petite Chez Scheme is built from the same sources as Chez Scheme, with all but the compiler sources included.
