# This file is meant to be included into a target to provide an action
# to compute information about individual interfaces defined in a component.
#
# To use this, create a gyp target with the following form:
# {
#   'target_name': 'interfaces_info_individual_component',
#   'dependencies': [
#     'generated_idls_target',
#   ],
#   'variables': {
#     'static_idl_files': '<(component_static_idl_files)',
#     'generated_idl_files': '<(component_generated_idl_files)',
#     'component_dir': 'component',
#     'output_file':
#       '<(bindings_core_output_dir)/InterfacesInfoComponentIndividual.pickle',
#   },
#   'includes': ['path/to/this/gypi/file'],
# },
#
# Required variables:
#  static_idl_files - All static .idl files for the component, including
#    dependencies and testing.
#  generated_idl_files - All generated .idl files for the component.
#    (Must be separate from static because build dir not know at gyp time.)
#  component_dir - Relative directory for component, e.g., 'core'.
#  output_file - Pickle file containing output.
