+# This Makefile fragment is included by packages that use gmp.
+#
+# To use this Makefile fragment, simply:
+#
+# (1) Optionally define GMP_REQD to the version of gmp desired.
+# (2) Include this Makefile fragment in the package Makefile,
+# (3) Optionally define BUILDLINK_INCDIR and BUILDLINK_LIBDIR,
+# (4) Add ${BUILDLINK_TARGETS} to the prerequisite targets for pre-configure,
+# (5) Add ${BUILDLINK_INCDIR} to the front of the C preprocessor's header
+#     search path, and
+# (6) Add ${BUILDLINK_LIBDIR} to the front of the linker's library search
+#     path.
