# Include this file in any target that needs to use files generated from queue
#   etc. definitions.
#
# To use, create a target of the following form:
# {
#   'target_name': 'my_queues',
#   'type': 'static_library', # or any other type that can handle .cc files
#   'sources': [
#     'aos/example/Queue.q',

#   'variables': {
#     'header_path': 'aos/example',
#   },
#   'includes': ['path/to/queues.gypi'],
# },
# Code that depends on this target will be able to #include
#   "aos/example/Queue.q.h" and "aos/example/ControlLoop.q.h".
#
# using <http://src.chromium.org/svn/trunk/src/build/protoc.gypi> as an
# example of how this should work
