        GNU Guile is an implementation of the Scheme programming language, with
        support for many SRFIs, packaged for use in a wide variety of
        environments.  In addition to implementing the R5RS Scheme standard and
        a large subset of R6RS, Guile includes a module system, full access to
        POSIX system calls, networking support, multiple threads, dynamic
        linking, a foreign function call interface, and powerful string
        processing.
