+# $NetBSD: buildlink.mk,v 1.1 2001/05/24 08:53:56 jlam Exp $
+#
+# This Makefile fragment is included by packages that use readline().
+#
+# If readline() is not present in the base system through libedit, then a
+# dependency on devel/readline is added, the appropriate headers are linked
+# into ${BUILDLINK_INCDIR} (${WRKSRC}/include), and the appropriate libraries
+# are linked into ${BUILDLINK_LIBDIR} (${WRKSRC}/lib).
+#
+# To use this Makefile fragment, simply:
+#
+# (1) Optionally define USE_GNU_READLINE to force use of GNU readline.
+# (2) Optionally define READLINE_REQD to the version of GNU readline desired.
+# (3) Include this Makefile fragment in the package Makefile,
+# (4) Optionally define BUILDLINK_INCDIR and BUILDLINK_LIBDIR,
+# (5) Add ${BUILDLINK_TARGETS} to the prerequisite targets for pre-configure,
+# (6) Add ${BUILDLINK_INCDIR} to the front of the C preprocessor's header
+#     search path, and
+# (7) Add ${BUILDLINK_LIBDIR} to the front of the linker's library search
+#     path.
+#
+# NOTE:	You may need to do some more work to get libedit recognized over
+#	libreadline, especially by GNU configure scripts.
