<!--

  Checkstyle configuration that checks the sun coding conventions from:

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

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

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

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

  - some best practices

  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.
