| 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. |
