<!--
Checkstyle configuration that checks the Google coding conventions from Google Java Style
that can be found at https://google.github.io/styleguide/javaguide.html.
Checkstyle is very configurable. Be sure to read the documentation at
http://checkstyle.sf.net (or in your downloaded distribution).
To completely disable a check, just comment it out or delete it from the file.
