# This Makefile fragment handles the common variables used by OCaml packages.
#
# Build def variables:
# OCAML_USE_OPT_COMPILER 
# if set to yes, will enable optimised (native code) compilation
# default value: depends on architecture
#
# PLIST variable:
# PLIST.ocaml-opt for files only installed when using the optimised compiler
# Set based on OCAML_USE_OPT_COMPILER
# 
# Package-settable variables:
# OCAML_USE_FINDLIB
# package uses findlib infrastructure
# OCAML_USE_OASIS [implies OCAML_USE_FINDLIB]
# package uses oasis infrastructure
# OCAML_USE_OASIS_DYNRUN [implies OCAML_USE_OASIS]
# package uses oasis.dynrun
# OCAML_USE_OPAM
# package uses OPAM
# OASIS_BUILD_ARGS
# arguments for oasis build
# Set by this file:
# OCAML_SITELIBDIR
