      '' Guile-Cairo wraps the Cairo graphics library for Guile Scheme.

         Guile-Cairo is complete, wrapping almost all of the Cairo API.  It
         is API stable, providing a firm base on which to do graphics work.
         Finally, and importantly, it is pleasant to use.  You get a powerful
         and well-maintained graphics library with all of the benefits of
         Scheme: memory management, exceptions, macros, and a dynamic
         programming environment.
