The `<base>` tag below is present to support two advanced deployment options:
1) Differential serving. 2) Serving from a non-root path.
Instead of manually editing the `<base>` tag yourself, you should generally either:
a) Add a `basePath` property to the build configuration in your `polymer.json`.
b) Use the `--base-path` command-line option for `polymer build`.
