# armel binaries where cpu transparency is set to qemu-arm and
# mapping mode is emulate.
#
# For example if one wants to debug standalone gui binary (maemopad)
# run inside emulation mode:
# run-standalone.sh `sb2-qemu-gdbserver-prepare` ./maemopad
# and qemu should start listening gdbserver port.
