59Welcome to the $OBSD installation program.
60
61This program can install $OBSD, or upgrade an existing
62OpenBSD installation.
63
64At any prompt except password prompts you can escape to a shell by
65typing '!'. Default answers are shown in []'s and are selected by
66pressing RETURN.  At any time you can exit this program by pressing
67Control-C, but exiting during an $MODE can leave your system in an
68inconsistent state.

79NOTE: Once your system has been upgraded, you must manually merge any
80changes to files in the 'etc' set into the files already on your system.
