# Author: Stanislav Sedov <ssedov@mbsd.msk.ru>
#
# Feel free to send any comments and suggestions to maintainer.
#
# Currently recognised variables are:
#
# USE_OCAML		-	Set if your port uses OCaml to build/install.
# NO_OCAML_BUILDDEPENDS	-	Don't add ocamlc to BUILD|EXTRACT|PATCH_DEPENDS.
# NO_OCAML_RUNDEPENDS	-	Don't add ocamlc to RUN_DEPENDS.
# USE_OCAML_FINDLIB	-	Set if your port uses ocamlfind to install
#				packages. Package direcories will be
#				automatically deleted.
# USE_OCAML_LDCONFIG	-	Set if your port installs shared libraries
#				into ocaml site-lib dir. OCaml ld.conf file
#				will be automatically processed.
# USE_OCAMLFIND_PLIST	-	Add contents of findlib target directories
#				automatically.
# USE_OCAML_WASH	-	Set if your port wants to automatically
#				purge shared Ocaml dirs on uninstall. It's
#				useful when installing to non-standard PREFIX
# OCAML_PKGDIRS		-	Directories under site-lib to be processed
#				if USE_OCAML_FINDLIB specified.
#				Default: ${PORTNAME}
# OCAML_LDLIBS		-	Directories under PREFIX to be automatically
#				added/removed from ld.conf
#				Default: ${OCAML_SITELIBDIR}/${PORTNAME}
