+# This script is intended for use with separately linked ROM and RAM.
+# It creates EITHER a linker script that satisfies references made by RAM
+# applications to ROM symbols OR a linker script that forces symbols to
+# be included in a ROM image.
+#
+# The option "--addrs" causes the RAM linkage script to be generated
+# and the option "--externs" causes the ROM linkage script to be generated.
+#
+# Example usage:
+#     make_ld.sh --addrs athos.rom.out athos.rom.symbols > rom.addrs.ld
+#     make_ld.sh --externs athos.rom.symbols > rom.externs.ld
