%  Questo pacchetto è stato realizzato per velocizzare la scrittura 
%  di documenti da parte di studenti della facoltà di Ingegneria dell'informazione.
%  E' in particolar modo indicato per gli studenti iscritti in facoltà di
%  Ingegneria delle Telecomunicazioni.
%
%  Si ringrazia per i suggerimenti sui simboli da usare Alessio Sanna e
%  per i preziosi consigli pratici di programmazione Enrico Gregorio.
