12.1 GNU Guile Integration
==========================

GNU 'make' may be built with support for GNU Guile as an embedded
extension language.  Guile implements the Scheme language.  A review of
GNU Guile and the Scheme language and its features is beyond the scope
of this manual: see the documentation for GNU Guile and Scheme.

   You can determine if 'make' contains support for Guile by examining
the '.FEATURES' variable; it will contain the word GUILE if Guile
support is available.

   The Guile integration provides one new 'make' function: 'guile'.  The
'guile' function takes one argument which is first expanded by 'make' in
the normal fashion, then passed to the GNU Guile evaluator.  The result
of the evaluator is converted into a string and used as the expansion of
the 'guile' function in the makefile.

   In addition, GNU 'make' exposes Guile procedures for use in Guile
scripts.
