 # Paths to the JSON files are kind of gross. They're stored in the gypi
 # relative to //components, since that's the working directory gyp seems
 # to use for all of the components. When we depend on them here, we need
 # to remove the leading domain_reliability, since *our* working directory
 # is one level deeper. When we call bake_in_configs.py, we need to give
 # it a properly-rebased path to //components so it can properly join the
 # paths relative to that and find the JSON files.
