+# This file is simply an example of what can be done using the new binary
+# and symbol table output functions. It produces a byte array with the
+# symbols in the object as array references within it.
+#
+# The output is a Linux OMAGIC binary created by ld86 -N, this means the
+# object can be linked directly to C-functions created by the same GCC that
+# compiled ld86.
+#
+# Use it in a makefile:
+#
+# .s86.o:
+#	as86_to_data $*.s86 $*.o $(AS86FLAGS)
