  "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.")
