Overview

This postprocessor rewrites ‘//sourceMappingURL=` comments to include the hashed filename of the map. As a side effect, the default implementation also replaces relative sourcemap URLs with absolute URLs, including the CDN domain. We want to preserve the relative nature of the URLs, so that compiled JS is portable across sites with differing CDN configurations.
