Migration of TDG:HTML_CSS to new PEAR Manual

Hello all, I've finally include The Definitive Guide (TDG), my external doc, to the new PEAR Manual. It was so easy (a very pleasure). I didn't like idea to do it before PhD was available and provides a such facility ! Thanks to all PhD team, and especially Christian Weiske, without who this guide (and the others one I've written) won't certainly be included into new PEAR Manual. Last but not least, a wink to all developers/leaders that provides a stable version of their package without any doc. Even it's a PEAR standard rule, and I regret that it not followed at 100%, ... Developers / Leaders, you've no excuse now to write a doc/guide. Let's talk your pencil, even it's not a Best Seller, a draft is better than nothing. Laurent Laville
