-/**
- * A script for printing a JSON dump of HTML diff data. In particular, this
- * lists a map of `dart:dom` methods that have been renamed to `dart:html`
- * methods without changing their semantics, and `dart:dom` methods that have
- * been removed in `dart:html`. As a heuristic, a `dart:html` method doesn't
- * change the semantics of the corresponding `dart:dom` method if it's the only
- * corresponding HTML method and it has the corresponding return type.
- *
- * The format of the output is as follows:
- *
- *   {
- *     "renamed": { domName: htmlName, ... },
- *     "removed": [name, ...]
- *   }
- *
- * Note that the removed members are listed with the names they would have in
- * HTML where possible; e.g. `HTMLMediaElement.get:textTracks` is listed as
- * `MediaElement.get:textTracks`.
