<!--

  Checkstyle configuration that checks the sun coding conventions from:

    - the Java Language Specification at
      https://java.sun.com/docs/books/jls/second_edition/html/index.html

    - the Sun Code Conventions at https://java.sun.com/docs/codeconv/

    - the Javadoc guidelines at
      https://java.sun.com/j2se/javadoc/writingdoccomments/index.html

    - the JDK Api documentation https://java.sun.com/j2se/docs/api/index.html

    - some best practices

  Checkstyle is very configurable. Be sure to read the documentation at
  https://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.
