 Guile is a Scheme implementation designed for real world programming,
 providing a rich Unix interface, a module system, an interpreter, and
 many extension languages. Guile can be used as a standard #! style
 interpreter, via #!/usr/bin/guile, or as an extension language for
 other applications via libguile.
