The name Guile stands for GNU’s Ubiquitous Intelligent Language for Extensions. It provides a Scheme interpreter conforming to the R4RS language specification. This section describes use of Guile as an extension language for GNU Radius. It assumes that the reader is sufficiently familiar with the Scheme language. For information about the language, refer to Revised(4) Report on the Algorithmic Language Scheme. For more information about Guile, see Overview in The Guile Reference Manual.

authentication request is triggered by the Scheme-Procedure
attribute; the invocation for an accounting request is triggered
by the Scheme-Acct-Procedure attribute. The following sections
address these issues in more detail.
