+
+ Based on http://checkstyle.sourceforge.net/sun_style.html, the
+ 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.sourceforge.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.
