In my previous diary entry, I somewhat sarcastically obeyed the letter of the BSDish-with-advertising licence of cl-pdf. Since then, Marc Battyani wrote to me to say that he was removing the advertising clause from the licence of cl-pdf (and cl-typesetting), replacing it with a request (not part of the licence) to acknowledge its use in significant applications, to assist in promoting the Common Lisp language. Thanks, Marc, both for the software and for the friendlier licence.
