Sources are copyrighted but freely used acknowledging the notices
on the top of each source code.
Documents are placed in public domain, though we may update
the contents time to time.

Major features of 1.2 version are:
1. YY-client is tested with Lucid 4.0 (Lucid CLOS), Allegro 3.1.13 (PCL), 
   Allegro 3.1.17 (International version, PCL), and Symbolics Genera 8.0
   (Symbolics CLOS).
   YY-server is mainly tested on Sun4 SunOS4.1 and X11R4.
   (And is working on several other UN*X and/or X11R3 like titan.)
2. Updated YY-server to cope with new features.
3. Updated YY-Protocol (between YY-server and YY-client) specification
   with the introduction of the page mode (for text oriented interaction)
   and viewport mode (for high speed graphic outputs).
4. Event processing, popup menu and several primitives are refined.
5. Many bug fixes and improvements of 1.11alpha.

Further schedule:
0. Refinement of YYAPI specification.
   (Yes, we had not made enthusiastic efforts on improving API specification
   yet, since we like to adopt standards for external interfaces and
   had not enough time to take care of outlooks.)
1. More enhancements on Graphics, animation area.
2. UI tools enhancements.
3. Versions for mainframe Common Lisps are under development.
4. UK researchers told us that the Eulisp is running on top of YY.
   We will welcome such experimentation.
5. Attempt to start the discussion with CLIM to have an unified 
   external specification. (YY and CLIM made a joint statement for it
   on 1990/02/14.)
6. Continuous trial to obtain much higher performance on the
   communication between YY-client process and YY-server process.

                What is YYonX
                                               1990/11/05

1. What is YY ?
---------------
YY is a network oriented window toolkit for Common Lisp.
YYonX is an implementation of YY for X-window.

2. YYonX characteristics ?
--------------------------
The Major Characteristics are:
1. It is a pilot implementation of YY for X.
2. It used a server/client model.
 YY-server is a X-client for low level stuffs.
 YY-client is a X-client for an application part and API.
3. CLOS oriented portable tool kit.
4. Never make a Xlib (CLX) call by user.
5. There is YY-Protocol for the communication between YY-server and
 YY-client.
 YY-Protocol enables the co-operation of YY-server and YY-client
 over TCP/IP, and has a highly compressed format.
6. For example, you may use a SUN3/60 X-server, a SUN4/260 YY-server,
and a YY-client on a different machine to execute YYonX based application.
7. Tested X-windows are X11R4, X11R3.
