<!-- 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. -->
