CaSU -- communications & status utilities.


Intro:
------

CaSU is a collection of programs for communicating with, and showing
the status of, other users (especially your friends). The package
currently consists of:
    flon --	lists your friends who are logged on
    to --	sends a short message to another user


_flon_ uses the `$HOME/.friends' file to instruct it on which users to
selectively display.  The file eg.friends contains sample information.
The $FLON environment variable is also used by _flon_.  Refer to the
manual (source form is `FLON.rof') for more details.

_to_ uses the `$HOME/.torc' file to store various parameters.  The
various settings in this text file can either be directly edited,
or set via command line options.  The eg.torc file contains a sample. 
Refer to the manual (source form is `TO.rof') for more details.


Quick Installation Notes:
-------------------------
From your favourite shell, run:
	sh ./configure
	make
	make install
	make install.man


Some people may wish to install the manual pages formatted. If this
is the case, type:
	make install.catman

By default, _flon_ will install a hard link to itself with the name of
`who' (to use _flon_ as who). If you don't want this behaviour, modify
the Makefile and clear the `who_prog =' variable.

_to_ may need to be installed by the system administrator if your system
limits who can access a user's tty. During configuration, if a message
such as:
    checking mesg y permissions
    - `to' is setgid to group 5
appears, then this is the case.


CaSU 3.3.3 has successfully been ported (in that the author has personally
tested the auto-configured scripts) to the following architectures:
    A/UX 3.0, Linux, NetBSD 0.9, Solaris 2, SunOS 4.1.3, Umax 2.4
Flon and To (at various stages of their development) have also been
ported to the following architectures: (and theoretically should still
work without problems)
    386BSD 0.1, AIX, Dynix, Irix 4, SCO Unix, SVR4 (non-Solaris)


Future enhancements:
--------------------
- enhance package to become the rcaid (remote communications and
  interactive diary) currently being designed by myself and
  Andrew Vanderstock, which contains the following subsystems:
    - remote to (``rto'')
    - remote flon (``rlon'')
    - remote calendar (``rcal'')
    - remote pin-board (``rpin'')


Bug reports, fixes, suggestions, and enhancements would be gratefully
