+/** \file cons.saver.h
+ *  \brief Header: general purpose Linux console screen save/restore server
+ *
+ *  This code does _not_ need to be setuid root. However, it needs
+ *  read/write access to /dev/vcsa* (which is priviledged
+ *  operation). You should create user vcsa, make cons.saver setuid
+ *  user vcsa, and make all vcsa's owned by user vcsa.
+ *  Seeing other peoples consoles is bad thing, but believe me, full
+ *  root is even worse.
