      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.
