  * Common logic to make it easy to run the polymer linter and deploy tool.
  *
  * The functions in this library are designed to make it easier to create
  * `build.dart` files. A `build.dart` file is a Dart script that can be invoked
  * from the command line, but that can also invoked automatically by the Dart

  * **Example 3**: Runs the linter, but conditionally does the deploy step. See
  * [parseOptions] for a description of options parsed automatically by this
  * helper library.

  * **Example 5**: Like the previous example, but indicates to the linter and
