{The incredible tale of the author who didn't want to do the publisher's job} {Didier Verna} {In this talk, I will relate a recent experience of mine: writing a book chapter for a publisher who doesn't have a clue about typesetting. I will confess my futile attempt at using \TeX\ for writing the chapter in question. I will then describe the hell that descended upon me for daring to do that. I will however admit that the hell in question would have been even greater, had I not done so. I will give this talk both crying and laughing, and I will seek your comfort. }
