;; Commentary:
;;
;; Standard build procedure for packages using ocaml. This is implemented as an
;; extension of `gnu-build-system'.
;;
;; OCaml packages don't use a single standard for their build system. Some use
;; autotools, other use custom configure scripts with Makefiles, others use
;; oasis to generate the configure script and Makefile and lastly, some use
;; custom ocaml scripts.
;;
;; Each phase in the build system will try to figure out what the build system
;; is for that package. Most packages come with a custom configure script and
;; a Makefile that in turn call custom build tools. Packages built with oasis
;; will have a `setup.ml' file in the top directory, that can be used for all
;; phases. In that case the Makefile is here only to call that script. In case
;; the setup.ml do not work as expected, the @var{use-make} argument can be
;; used to ignore the setup.ml file and run make instead.
;;
;; Some packages use their own custom scripts, `pkg/pkg.ml' or
;; `pkg/build.ml'. They can be used here too.
;;
;; Code:
(define %ocaml-build-system-modules
;; Build-side modules imported by default.
`((guix build ocaml-build-system)
