const String HOOKS_API_USAGE = """
// The code supports the following hooks:
// dartPrint(message):
// if this function is defined it is called instead of the Dart [print]
// method.
// dartMainRunner(main, args):
// if this function is defined, the Dart [main] method will not be invoked
// directly. Instead, a closure that will invoke [main], and its arguments
// [args] is passed to [dartMainRunner].
// dartDeferredLibraryLoader(uri, successCallback, errorCallback):
// if this function is defined, it will be called when a deferred library
// is loaded. It should load and eval the javascript of `uri`, and call
// successCallback. If it fails to do so, it should call errorCallback with
// an error.
// defaultPackagesBase:
// Override the location where `package:` uris are resolved from. By default
// they are resolved under "packages/" from the current window location.
