Acknowledgments
It is i mpossible to write a book such as this without the assistance and support from
many quarters.
Valuable assistance came from:
Natali Arn (drawings), Vincenne Buonpane (publishing), Clean Slate (design), Sue
Buri (logistics), Dane Kurth (translation) and Marco Zingg (support).
In addition to their time-consuming jobs, they all spent time in order to help me to
realize this project. I take this opportunity of thanking them.
Numerous other people also helped indirectly to make this possible. Representing
them all I would like to thank:
Paul Aieta
Tim Breen
