#   'target_name': 'interfaces_info_component',
#   'dependencies': [
#       'interfaces_info_individual_base_component',
#       'interfaces_info_individual_component',

#
# Required variables:
#  input_files - Pickle files containing info about individual interfaces, both
#    current component and any base components.
#  output_file - Pickle file containing output (overall info).
