Node:Reference Layout, Previous:Scheme Only, Up:API Overview
This part of the reference manual documents all of Guile's core Scheme-level language and features in functionally-related groups. Where a particular section of the manual includes both R5RS-compliant parts and Guile-specific extensions, the text indicates which parts of the documentation describe R5RS behaviour and which parts describe Guile extensions.
For a quick way of identifying the parts of Guile that implement R5RS-compliant features, see the R5RS index: R5RS Index.
