Acknowledgments

Viper, formerly known as VIP-19, was written by Michael Kifer. Viper is based on the original VIP package by Masahiko Sato and on its enhancement, VIP 4.4, by Aamod Sane. This manual is an adaptation of the manual for VIP 4.4, which, in turn, was based on Sato's manual for VIP 3.5.
