   3 @chapter Introduction to Guile Scheme
   4
   5 Guile's core language is Scheme, which is specified and described in the
   6 series of reports known as @dfn{RnRS}.  @dfn{RnRS} is shorthand for the
   7 @iftex
   8 @dfn{Revised$^n$ Report on the Algorithmic Language Scheme}.
   9 @end iftex
  10 @ifnottex
  11 @dfn{Revised^n Report on the Algorithmic Language Scheme}.
  12 @end ifnottex
  13 The current latest revision of RnRS is version 5
  14 (@pxref{Top,R5RS,,r5rs}), and Guile 1.4 is fully compliant with the
  15 Scheme specification in this revision.
  16
  17 But Guile, like most Scheme implementations, also goes beyond R5RS in
  18 many ways, because R5RS does not give specifications (or even
  19 recommendations) regarding many issues that are important in practical
  20 programming.  Some of the areas where Guile extends R5RS are:
  21
  22 @itemize @bullet
  23 @item
  24 Guile's interactive documentation system
  25
  26 @item
  27 Guile's support for POSIX-compliant network programming
  28
  29 @item
  30 GOOPS -- Guile's framework for object oriented programming.

  41 This part of the reference manual documents all of Guile's core
  42 Scheme-level language and features in functionally-related groups.
  43 Where a particular section of the manual includes both R5RS-compliant
  44 parts and Guile-specific extensions, the text indicates which parts of
  45 the documentation describe R5RS behaviour and which parts describe Guile
  46 extensions.
  47
  48 For a breakdown of Guile's core language and features in terms of what
  49 is R5RS-compliant and what is Guile-specific, see the corresponding
  50 indices: @ref{R5RS Index} and @ref{Guile Extensions Index}.
