21. Gestion des protocoles internet
***********************************

Les modules documentés dans ce chapitre implémentent des protocoles
relatifs à Internet et à ses technologies relatives.  Ils sont tous
implémentés en Python. La majorité de ces modules nécessitent la
présence du module "socket" lui même dépendant du système, mais fourni
