-# This target contains only those files that are shared by the Device Sensors
-# implementation and all Device Sensors clients, including Blink. Add a file
-# here only if it meets the following constraints:
-# (1) It is *necessary* to use the file to consume Device Sensors (the
-# current files define structs that are used as a consistent interpretation of
-# shared memory by the Device Sensor and its clients).
-# (2) The file has no dependencies on the STL or Chromium code and will not
-# grow them over time (the current  files are POD structs and will necessarily
-# stay that way due to their above-described purpose).
-# If a file does not meet these constraints, it cannot be used by the Blink
-# client and should be placed in the "full" target below. Similarly, clients
-# without Blink's constraints should depend on the "full" target below rather
-# than this one.
-# Consult {platform-architecture-dev, services-dev}@chromium.org in the case
-# of any uncertainty.
