Wafe 0.94 is mostly a bug fix distribution for several platforms.

Differences between Wafe 0.93 and 0.94:
    -  simple editor xwe 
       (mostly by Dov Grobgeld, dov@menora.weizmann.ac.il)
    -  experimental MIME support for quoted printable texts
    -  bugfix for getValue of 2-byte values under hpux or AIX
    -  bugfix for multiple double values in one setValues command
    -  bugfixes in plotter widget sources
    -  based on plotter-6.0pl7 (instead of 6.0 in Wafe 0.93)
    -  based on tcl 6.6 (instead of 6.5 in Wafe 0.93)
    -  based on xpm 3.2e (instead of 3.2c in Wafe 0.93)
    -  easier installation on sun systems 
       (due to change from tcl 6.5 to 6.6)
    -  several changes in application programs
    -  more small sample scripts (in $WAFE/src/tcl/*) such as 
       the following file selector

	list browse topLevel \
	   callback {sV topLevel title "Selected: %s"} \
	   list [split [exec /bin/ls -1] \n]
	realize
       
       The scripts ending with .tcl are for the Athena version,
       the others are for Motif.

ANNOUNCEMENT:

    Due to several requests a new mailing list for Wafe was 
    installed at our site using the listserv package. In order 
    to subscribe, send a mail with the mailbody

Wafe 0.94 contains no additional or changed wafe commands compared 
to version 0.93.

Here is the updated README file of the WAFE distribution. 
======================================================================

    WHAT IS WAFE

    Wafe (Widget[Athena]front end) is a package that implements 
    a symbolic interface to the Athena widgets (X11R5) and OSF/Motif. 
    A typical Wafe application consists of two parts: a front-end (Wafe) 
    and an application program which runs typically as a separate 
    process. The application program can be implemented in an arbitrary
    programming language and talks to the front-end via stdio.
    Since Wafe (the front-end) was developed using the extensible
    TCL shell (cite John Ousterhout), an application program can
    dynamically submit requests to the front-end to build up the
    graphical user interface; the application can even down-load
    application specific procedures into the front-end. 

    In opposite to the described two process frontend approach, wafe 
    applications can also be written purely in TCL, in which case only 
    one process is needed.

    The distribution contains sample application programs in Perl,
    GAWK, Prolog, TCL, C and Ada talking to the same Wafe binary.
    Most of the following demo applications are implemented in 
    Perl 4.0.36:

c        - xwafedesign: interactive design program for wafe applications
	 - xwafeftp:    FTP front-end
c	 - xwafemail:   Mail user front-end with faces, using elm aliases
c	 - xwafenews:   NNTP based newsreader, using elm aliases
	 - xwafegopher: a very simple gopher interface
c	 - xdirtree:    tree directory browser
	 - xprojektor:  white board program for the classroom
	 - xbm:         bitmap and pixmap viewer
	 - xwafemc:     multiple choice test answering program
	 - xruptimes:   rwho monitor like xnetload
	 - xnetstats:   network statistics, front-end for netstat -i <interval>
	 - xvmstats:    system statistics, front-end for vmstat -i <interval>
	 - xiostats:    io statistics, front-end for iostat -i <interval>
	 - xwafeping:   pings several machines an show up-status
	 - xwafecf:     a simple read only card-filer
	 - xwafetel:    a simple read only Oracle front-end for looking up
	                telephone numbers
	 - xwafeora:    a more elaborated Oracle front-end with updates 
	                capable to model an entity type with distinct
	                predicate defined subtypes, allowing multi valued 
                        attributes (it comes with sample applications 
                        "filing management" and "paper base") doing field 
                        completion and other funky stuff

	 - primfakt.awk:    primfakt program in GAWK using wafe
	 - primfakt.prolog: primfakt program in Prolog using wafe
	 - primfakt.perl:   primfakt program in Perl using wafe
	 - primfakt.c:      primfakt program in C using wafe
	 - primfakt.a:      primfakt program in Ada using wafe
	 - cprimfakt.c:     native C implementation of primfakt (single process)
	 - xprimfakt.tcl:   primfakt program in TCL using wafe (single process)

	 - perlwafe: an example program calling wafe as a subprocess of the
	   application program (normally, it is the other way round).


    HOW CAN WAFE BE USED AS A FRONTEND 

    Suppose you have an application program named "app". If we
    install a link like "ln -s wafe xapp" and execute "xapp ", the
    program "app" is spawn as a subprocess of wafe and connects its
    stdio channels with the front end.  Lines written from the
    application program to stdout are read from Wafe. If the line
    starts with a certain character (such as %) Wafe tries to
    interpret the remainder of the line as TCL command.  The
    standard TCL shell has been extended with new commands
    exploiting the X Toolkit, the Athena widget set, the 
    OSF/Motif widget set and the XPM library to build up
    user interfaces with the window system named X.

    In most example programs of the distribution the application program
    is run as a subprocess of wafe, one example (perlwafe) shows the 
    opposite constellation where the "link magic" is not needed.

    ADVANTAGES of Wafe

	-  application program can be written in wide range of programming
	   languages
	-  relatively high level interface to widget applications
	-  single wafe binary for multiple applications
	-  better refresh behavior when application program is busy
	-  click ahead
	-  better separation between user interface and
	   application program matters 
	-  no need to hack C code
	-  easier migration from existing ascii based programs to
	   X-window applications



    REQUIREMENTS FOR APPLICATION PROGRAMS

    In order to use Wafe in a two process setup, an application program 
    must be able to write **LINEBUFFERED** (or unbuffered) to stdout (the 
    application program must at least be able to flush the buffer) and 
    to read from stdio. The application program determines the syntax 
    in which Wafe talks back.


    AVAILABILITY

    Wafe was developed on DECstations 5000/200 under Ultrix 4.2
    using X11R5, and has been tested on a SparcStation 1+ under
    SunOS 4.1, RS6000/320 under AIX and on a HP 9000/720 under hpux
    8.05. Wafe can be compiled under X11R5 and X11R4. The preferred
    program-to-program communication is done via socketpair,
    support for PIPES and SYS V streams is included for systems
    without the socktepair system call.

    NECESSARY, BUT NOT INCLUDED 

    Most application of the distribution are written in Perl. 
    Perl 4.036 is needed to run these applications. Two applications 
    will need oraperl.  Only user with an Oracle license might find 
    wafeora and wafetel useful. User might wish to compile wafe with 
    the 3d Athena Widget library Xaw3d-0.5.tar.Z. Pointers to the 
    source can be found in the INSTALL file.


    PRERELEASE

   The current distribution is a prerelease (version 0.94). The final
    version (whatever final means) will be posted after we got some 
    feedback/suggestions from the network.

   Wafe 0.94 can be obtained via anonymous ftp from

	    ftp.wu-wien.ac.at:pub/src/X11/wafe/wafe-0.94.tar.Z

   (for people without name server: the ip address is 137.208.3.4)
    A split up version is available from the same directory.

   Does anybody know whether or not it is legal to make a
   OSF/Motif binary of Wafe available?
