/*! \brief Fonction principale: on peut choisir le nombre de points
* en utilisant l'option "-nX" où X est un entier strictement
* positif.
* \remark Mettre opterr a 0 equivaut a supprimer volontairement les messages d'erreur renvoyes par getopt
* lors de la lecture d'options non prevus sur la ligne de commande. Dans ces cas, l'erreur est traitee grace au
* fait que getopt retourne la valeur '?', qui est donc traitee a part
* \remark "n:" signifie que l'option n s'accompagne de la lecture immediate d'une valeur. Il ne faut pas
* laisser d'espace entre -n et le nombre tape. Exemple: two -n1000.\par
* La lecture est effectuee par un sscanf (lecture d'une chaine supposee formattee) sur l'argument ad hoc, optarg,
* declare dans les routines de lecture de la ligne de commande.
