-"""Bootstrap Chrome Telemetry by downloading all its files from SVN servers.
-
-Requires a DEPS file to specify which directories on which SVN servers
-are required to run Telemetry. Format of that DEPS file is a subset of the
-normal DEPS file format[1]; currently only only the "deps" dictionary is
-supported and nothing else.
-
-Fetches all files in the specified directories using WebDAV (SVN is WebDAV under
-the hood).
