+# Makefile for linking with mapfiles.
+#
+# NOTE: Not using a mapfile will expose all your extern functions and
+#	extern data symbols as part of your interface, so unless your
+#	extern names are safe from being mistaken as names from other
+#	libraries, you better use a mapfile, or use a unique naming
+#	convention on all your extern symbols.
+#
+# The mapfile will establish versioning by defining the exported interface.
+#
+# The mapfile can also force certain .o files or elf sections into the 
+#   the different segments of the resulting library/program image.
+#
+# The macro FILES_m can contain any number of mapfiles.
+#
+
+# Always make sure 'all' is the default rule
+mapfile_default_rule: all
