Free interpreter for Chez Scheme system

Petite Chez Scheme is a complete Scheme system that is fully compatible with Chez Scheme but uses high-speed threaded interpreter technology in place of Chez Scheme’s incremental native-code compiler. Programs written for Chez Scheme run unchanged in Petite Chez Scheme, as long as they do not depend specifically on the compiler. In fact, Petite Chez Scheme is built from the same sources as Chez Scheme, with all but the compiler sources included.

Petite Chez Scheme was conceived as a freely distributable run-time environment for compiled Chez Scheme applications. To serve this purpose, it needed to have a complete run-time environment, including, for many applications, a working evaluator. The result is a system that is useful not only to our customers for the applications they distribute, but also to people who want to use a top-quality Scheme system and can’t justify purchasing Chez Scheme.
