README for ups - the package delivery system

ups is a system (actually just two programs) for delivering files between
users.  It works just like mail, except that accepting delivery implies
the movement of files.  Basically, a user just types to the shell the
following:
	ups user file1 file2 ...
this will cause the files file1, file2, ... to be copied into a spool area
and a mail message to be sent to 'user' informing them that there are files
awaiting them in ups.  To receive the files a user simply types 'ups' to
the shell and gets a list of files which are awaiting delivery and is
asked if they wish to accept delivery in the current directory.

What's required

ups was written for a 4.3bsd network of vaxes.  It will probably work on
a 2.9 or 4.2 system without a lot of work.  Other machines will certainly
require work.

Installation

	1)  Add ups to the table of known ports in /etc/services as follows:

	ups	600/tcp

	2)  Add ups to the inetd configuration file /etc/inetd.conf:

	ups	stream	tcp	nowait	root	/usr/local/lib/upsd	upsd

	3) Make ups and upsd by just saying "make all"
	
	4)  And finally install ups and upsd.  We installed upsd in /usr/local/lib 
	    (as shown above) and this is where make install will put it.
	     
	We also added a line to our standard .login file of the form: ups -q.  This will 
	inform users at login time if files are awaiting them.
