[PEPr] Comment on HTML::HTML_Libravatar

Hi. This is a great start. 1.) run phpcs on your code to find many small issues with coding standards 2.) your example code creates a new object and calls a method on the object but the URL method is documented as @static and uses $this::foo() internally. I recommend just using non-static method access. 3.) The organization of the code doesn't match the PEAR standards. You should have: / -docs/ -LICENSE -package.xml -Services/ --Libravatar.php -- http://pear.php.net/pepr/pepr-proposal-show.php?id=658
