        "Chibi-Scheme is a very small library with no external dependencies
        intended for use as an extension and scripting language in C programs.
        In addition to support for lightweight VM-based threads, each VM itself
        runs in an isolated heap allowing multiple VMs to run simultaneously in
        different OS threads.")
