# If you are compiling for an embedded Linux system, you may need to change
# the value of MX_LINUX_TARGET.  At present, the primary usage of this
# definition is to select special subsets of MX drivers for small systems
# that do not have enough memory to load all of the available MX drivers.
# Unless you are working with embedded systems, you should probably leave
# this at the default value of 'default'.
#
# If you have never heard of the term "target" in this context, then you
# should definitely leave this option alone.
