downloadgunmake-c992c4d80f51540699f33fed067caf6b7c38df79.tar.gz
Add GNU Guile as an optional embedded scripting language for make.
On configure-enabled systems, configure will detect Guile installed (using pkg-config, which is how GNU Guile is distributed) and enable it if so. On all non-configure-enabled systems, currently, the default is for Guile support to be disabled.
