+"""Starts the telemetry.components dev server.
+
+During normal usage of telemetry, telemetry.components files are
+compiled into standalone HTML+JS+CSS snippets that are then
+embedded in telemetry's various test resuls.
+
+The telemetry.components dev server allows edit-reload style development of
+these components. To use, start the dev server, navigate to the URL the script
+prints, and run any of the tests listed. Reloading in the browser loads the
+latest content from disk, enabling a traditional web development workflow.
