The folder structure of this directory is needed in order to be able to
mirror the BrowserMap module to the public GitHub repository from
https://github.com/apache/devicemap-browsermap/. Having the BrowserMap
module on GitHub allows running TravisCI continuous integration builds
for every commit; see https://travis-ci.org/apache/devicemap-browsermap.

For more details please check https://issues.apache.org/jira/browse/INFRA-6220.
