VIOLA VERSION 0.5 (pre-release version)

	Viola : Visually Interactive Graphical User Interface Engine
	Copyright (c) 1991, All rights reserved by Pei Y. Wei

-------------------------------------------------------------------------------
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: users can directly, or through scripts,
	create and modify objects without the tedious edit/compile/link/run
	cycle usually associated with GUI prototyping.

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.
	Just make sure the LIB_DIR and LIBNAME variables are 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.

temporary fix:

	if viola fails to start up, probably because it couldn't find the
	stacks, use the -option feature:

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

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.
