     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.
