## protobuffer targets
# Detailed instructions on how to work with these rules can be found in the
# common-mk package.  These rules are for including protobufs that live in the
# dbus directory of the system_api repo. To add a new one from this location to
# the build, just add the name of the generated .cc file to the bindings
# variable and include approriate depends targets[.
#
# To add protobufs from a different location then you need to copy all the proto
# variables and use a new prefix for them, setting the path variable as you
# need.
