WHAT IS VIOLA

Viola is basically a graphical user interface toolkit with an
embedded command language. The interpretive nature of Viola enables
it to be highly interactive.

COPYRIGHT

Viola is available for the free public use. You may copy and use 
Viola for any purpose, as long as the copyright notice and permission 
in the sources are retained in all sources of derived works. Fees
for distribution or use of this software or derived works may only
be charged with express written permission of the copyright holder.

DEVELOPMENT STATUS

Viola is unofficially supported only by me, not by the Experimental
Computing Facility. Also, since I'm graduating next month (May'91),
Viola's future development is uncertain. I will, however, certainly
continue to make efforts to maintain it. 

WHERE TO GET VIOLA

Freely distributable source and binaries are available at ftp site
scam.berkeley.edu (Internet 128.32.138.1).
Look in directory "src/local/viola".

Currently supported binaries were compiled on:
DECstation 3100 (Ultrix T4.0-1)
SparcStation (SunOS Release 4.0.3c)

HOW TO COMPILE VIOLA

Try using the binary before diving into a compile frenzy.
Viola is written in plain C, uses X11R4 and has an mkmf Makefile.
Make sure the LIB_DIR variable is correct.
Viola can be installed anywhere in your path.

RUNNING VIOLA

You need to tell viola where to find the stack files. Also, since
some stacks make use of man pages, you should set the MANPATH
accordingly. Ie:

% setenv MANPATH "${MANPATH}:/usr/local/lib/viola/man1"
% setenv VIOLA "/usr/local/lib/viola/stacks"
% /usr/local/bin/viola

If viola executes and is able to find the default startup stacks,
you should see a small icon-like window with two pull-down menus 
on it.

MAILING LIST

I am very interested in your comments regarding all aspects of 
Viola -- bugs, design issues, application ideas, and stacks that
you build.

You can send comments to me by mailing to "wei@ic.berkeley.edu".

There is a Viola mailing list "viola-users@ic.berkeley.edu".
You can mail directly to the list, and if you wish to be on, or off,
the list, let me know.
