		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.
