Introduction to Guile Scheme
****************************

Guile's core language is Scheme, which is specified and described in the
series of reports known as "RnRS".  "RnRS" is shorthand for the
"Revised^n Report on the Algorithmic Language Scheme".  The current
latest revision of RnRS is version 5 (Note: R5RS.), and
Guile 1.4 is fully compliant with the Scheme specification in this
revision.

But Guile, like most Scheme implementations, also goes beyond R5RS in
many ways, because R5RS does not give specifications (or even
recommendations) regarding many issues that are important in practical
programming.  Some of the areas where Guile extends R5RS are:

   * Guile's interactive documentation system

   * Guile's support for POSIX-compliant network programming

   * GOOPS - Guile's framework for object oriented programming.
