#
# Parameters:
#   prebuilt_archive_base_path: Base path for the prebuilt archive.
#   debug_archive_base_path: Base path for the debug archive.
#   custom_package_path: The path to the package inside a custom chromium
#       build output directory.
#   selections (optional): Flavor choice. This allows flavor to be changed based
#       on other build args.
