# TODO :: Replace omapl137 with official support in GST (currently linking to omapl138)
# TODO :: Codec Server Environment Variables shouldn't be required
# TODO :: Add (and check) rc scripts for all targets (just copied for now) (365,6467,omapl137)
# TODO :: Check if CPPFLAGS_append is still required
# TODO :: Remove ENCODE/DECODE combo exports - these are not used anymore (check?)
