  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.
