RELEASE 5.1 OF THE SIEMENS RTL TILED WINDOW MANAGER
                  
is now available in the /contrib/rtl5.1 directory on
expo.lcs.mit.edu.  It includes C source code (with an
Imakefile) as well as as manuals and tutorials in Scribe, Tex,
Postscript, and plaintext formats.

It is quite similar to the beta release, with a few bug fixes,
and portability improvements (12 char filenames, xio.h)

This software is being submitted to the X Consortium for
inclusion on the contributor's tape for Release 3.  It will
also be submitted to comp.sources.x.

Due to limited resources, we are unable to distribute
tapes.  The size of the system precludes the use of
electronic mail for distribution.

Features of this distribution:

    - This is a tiled window manager.  Windows and
    icons do not overlap (except for transient and
    override-redirect windows).  Arbitrary tiled layouts
    are supported, not just columns.

    - Automatic strategies are provided for window
    placement and sizing.  The degree of automation
    is controlled by a variety of options.

    - Windows are decorated with titlebars,borders and
    gadgets. The size and presence of these decorations
    can be individually controlled.

    - Supports most of the X11R2 version of the conventions
    for Client / Window Manager communications, except
    for wm installation of colormaps

    - The user can save and restore window layouts.
    That is, RTL is a session manager as well as a
    window manager.

    - Both click-to-type and real-estate-driven
    focus models are available.

    -  The user can specify a separate icon area
    and control icon layout within it.

    - The wm will optionally write application-specific
    information over specified regions of pixmap icons.

    - The user can override the client's pixmap icon.
    A variety of snazzy icons are provided for the
    usual applications.
    
    - Users can perform group-iconification -- display
    a single icon for a group of top-level windows (for
    clients that define window groups).
    
    - Support is provided for both 3-button and 1-button
    mice.

    - Using preference files, users can organize
    applications in a class hierarchy, for purposes of 
    inheriting option settings.

The /contrib/rtl5.1 directory contains a README file as
well as a number of files in compressed tar format.
The README file contains complete instructions
for uncompressing the files, and for installing the
system.  A SUMS file is included as well, for checking on the
results of ftp.

Please note again, that due to limited resources,
we cannot send out tapes of the system or distribute
it via electronic mail.

We are happy to receive comments and questions,
and will do our best to respond to them.  Send

    Attn: Tiled Window Manager

This is the first tiled window manager developed that
supports arbitrary layouts, and is as much a research
vehicle as a production-quality window manager.
Consequently, there are an extremely large number of options
that may be set by the user (although naive users can
use the default option settings, or one of the preference
files distributed with the system).  We are particularly
interested in users' experiences with various option settings.

Enjoy!
