		    UNaXcess 1.00.02 Installation Script
		    ------------------------------------

	This script requires that (1) you have NOAUTOPATH defined, or
	(2) you be running as root.  If you are not running as root,
	the "mkconf" program cannot be installed.

	(On BSD systems, root permissions are required only if the
	UNaXcess owner does not exist.  Note that if you are not running
	as root, you will receive spurious error messages from chown.
	You may ignore these messages.)

Welcome to UNaXcess V1.00.02 -- a computer bulletin board system designed for the UNIX(R) operating system.  You're using the ONLY BBS which is designed to USE Unix's unique features to their fullest potential.

This conference is the general-purpose conference.  Use it for discussions that don't fit in any of the existing conferences.  But if it's liable to be large, consider making a new conference for it.

The basic UNaXcess commands are:

M - Enter the Message Base menu.
G - Exit UNaXcess.
F - Enter the File UDL Section.  UNaXcess is capable of file uploading and downloading with ASCII, Xmodem and Kermit (not all may be available on all systems).
? - Help.  Press it once for one-line descriptions, press it again for the help file.

Press BREAK or CONTROL C to stop a command.
Press CONTROL-\ (CONTROL plus backslash) for a fast logout.

The UNaXcess User's Guide is available in the File UDL Area for those who have File UDL access.
