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

+
+    - 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.

I know that the comments here are based on sun_checks.xml, but I just think that
would be better to just close the comments without adding extra spaces to align
them, since they can eventually get misaligned when the comments changes, like
here.
