# The armsd.ini file instructs armsd to load the shared string library so its
# EFT is located at the address assumed by dynlink.s. Here, we grep the
# assumed address from dynlink.s and the EFT's offset from the library's
# map file (maplib). We load the library at <address>-<EFT offset>.
# eg.
# armsd: getfile strlib 0x40000-0x0009c8
#                               ^^^^^^^^ value of EFT$$Offset from maplib
