-/// Some Transformers to maintain compatibility with the new `test` package,
-/// since it doesn't use normal dart script tags in html. We get around this by
-/// using two transformers:
-///   - A transformer to convert <lint rel="x-dart-test"> intro dart script tags
-///     so that they can be processed by the rest of the transformers normally.
-///   - A second transformer to convert the output back, so that the `test`
-///     package can find a <link rel="x-dart-test"> tag after all the
-///     transformations are done.
