Usage

Overview

The s2ci command (previously known as sci) invokes a Scheme interpreter. The language accepted by this interpreter is that defined in the essential portions of the Revised4 Report on the Algorithmic Language Scheme, with minor constraints and some additions. The Scheme interpreter is written in Scheme which has then been compiled using the Scheme-to-C compiler, s2cc.

Environment
