// This file is used by `generate_search_engine_icons.py` to locate the search
// engine icons within https://www.gstatic.com/android_search/search_providers/.
// These files are checked in at
// `google3/googledata/html/external_content/gstatic/android_search/search_providers/`.
// By default it will try to download an icon from
// "[...]/{engine}/xxxhdpi.png" and from "[...]/{engine}/{engine}_xxxhdpi.png".
// If the icon is located in a different subfolder, add the engine to
// `engine_aliases` with the subfolder name. If the icon has a different
// filename, add that filename to `non_default_icon_filenames`. If we don't need
// an icon for the engine, add it to `ignored_engines`.
{
  // Engines for which we don't need to download icons, either because we
  // already have them from another source or because they're not relevant to
  // the default search engine choice screen.
