Manu and Zborg for their comments and critics;
Fabrice, Guillaume, Aline, Virginie and Peggy for their numerous spellchecks and comments;
Anne, Pascal, Nathalie, Hélène, Samuel, Nicolas, Emmanuel and AltGr for proofreading, correcting and feedback;
Titi, Fred, Amandine, Nanar, Tocman and Poulpy for proofreading;
my friends, Amaury and Vanessa, and especially Daouda for discussing with me;
Thorpe, for all the information he provided me with;
all the mothers that have also read me, including mine;
