<!--

  Checkstyle configuration that checks the coding conventions based on http://maven.apache.org/plugins-archives/maven-checkstyle-plugin-2.14/config/sun_checks.html.

  Checkstyle is very configurable. Be sure to read the documentation at
  http://checkstyle.sf.net (or in your downloaded distribution).

  Most Checks are configurable, be sure to consult the documentation.

  To completely disable a check, just comment it out or delete it from the file.

  Finally, it is worth reading the documentation.
