Yesterday I mentioned the slides of the talk we gave on a new interface for latex class designers at TUG99. The slides are now available from the latex project web site http://www.latex-project.org/talks/tug99.pdf and also from the TUG99 website http://www.tug.org/TUG99-web/pdf/carlisle.pdf http://www.tug.org/TUG99-web/pdf/mittelbach.pdf http://www.tug.org/TUG99-web/pdf/rowley2.pdf (all four of these URL lead to the same document) Please note that this document was intended as informal `speaker notes' for our own use. We decided to make them available (the speaker notes as well as the slides that were presented) as several people requested copies after the talk. However they are _not_ in `polished' copyedited format intended for publication. David
