;; By default, we store patches, auxiliary files and bootstrap binaries
;; alongside Guile modules. This is so that these extra files can be
;; found without requiring a special setup, such as a specific
;; installation directory and an extra environment variable. One
;; advantage of this setup is that everything just works in an
;; auto-compilation setting.
