+# (1) Optionally define BZIP2_REQD to the version of bzip2 desired.
+# (2) Include this Makefile fragment in the package Makefile,
+# (3) Add ${BUILDLINK_DIR}/include to the front of the C preprocessor's header
+#     search path, and
+# (4) Add ${BUILDLINK_DIR}/lib to the front of the linker's library search
+#     path.
