/* SCENARIO  
   
  ° traitement des options :
    -v (affi version) -b bus, -r regexp file, -m message file, -n : nombre de recepteurs
    -t [type de test => ml (memory leak), tp (throughput)

    test memory leak
  ° fork d'un emetteur et d'un (ou plusieurs) recepteur : le recepteur s'abonne à toutes les regexps,
    se desabonne, se reabonne etc etc en boucle : on teste que l'empreinte mémoire
    de l'emetteur ne grossisse pas

    test throughput :
  ° fork d'un emetteur et d'un ou plusieurs recepteurs : les recepteurs s'abonnent à toutes les regexps
  ° l'emetteur envoie en boucle tous les messages du fichier de message
  ° l'emetteur note le temps d'envoi des messages
  ° l'emetteur envoie un die all et quitte
