                Congratulations! You have purchased an extremely fine
        device that would give you thousands of years of trouble-free 
        service, except that you undoubtably will destroy it via some 
        typical bonehead consumer maneuver. Which is why we ask you
        to PLEASE FOR GOD'S SAKE READ THIS OWNER'S MANUAL CAREFULLY
        BEFORE YOU UNPACK THE DEVICE. YOU ALREADY UNPACKED IT, DIDN'T
        YOU? YOU UNPACKED IT AND PLUGGED IT IN AND TURNED IT ON AND 
        FIDDLED WITH THE KNOBS, AND NOW YOUR CHILD, THE SAME CHILD WHO
        ONCE SHOVED A POLISH SAUSAGE INTO YOUR VIDEOCASSETTE RECORDER
        AND SET IT ON "FAST FORWARD", THIS CHILD ALSO IS FIDDLING
        WITH THE KNOBS, RIGHT?  AND YOU'RE JUST NOW STARTING TO READ 
        THE INSTRUCTIONS, RIGHT???  WE MIGHT AS WELL JUST BREAK THESE 
        DEVICES RIGHT AT THE FACTORY BEFORE WE SHIP THEM OUT, YOU 
        KNOW THAT?

Description
===========

Window Maker is the GNU window manager for the X Window System. It was designed
to emulate the look and feel of part of the NEXTSTEP(tm) GUI. It's supposed to
be relatively fast and small, feature rich, easy to configure and easy to use,
with a simple and elegant appearance borrowed from NEXTSTEP(tm).

Window Maker was designed keeping integration with GNUstep in mind and is the
"official" window manager for it. It is also part of the GNU project
(www.gnu.org) Read more about GNUstep further on this file.

Hints (information given by applications to integrate well with the window
manager) for Motif(tm) and NETWM are also supported (NETWM is used by KDE and
GNOME, so they are automatically supported as a result).  So you can replace any
of the window managers for these environments with Window Maker while keeping
most, if not all, of the native window manager functionality.

Window Maker was previously called WindowMaker.

Window Maker has no connection with Windowmaker, the software for making windows
and doors.


Documentation
=============

Read before asking.

* README files all over the source tree have info related to the stuff
in the directories. 

* INSTALL has installation instructions and some troubleshooting tips.
You're meant to read it before installing. it was not written just to fill up
space in the package.

* FAQ: Frequently Asked Questions. READ IT!!! FAQ.I18N is for
internationalization related questions.

* NEWS: list user visible changes from the previous version. Read it if
you are upgrading.

The Window Maker User's Guide can be downloaded from the official ftp
or web sites.

The User Guide explains how to use Window Maker, the configuration files
and options.


*** man pages

Type "man wmaker" in the shell prompt to get general help about Window Maker

HELP ME!!!
==========

There is a mailing list for discussing Window Maker at
wmaker-user@lists.windowmaker.org To subscribe to it, send a message to
wmaker-user-subscribe@lists.windowmaker.info

If you got a problem, ask there (after reading the docs, of course). The people
there is more likely to be able to answer your questions than we are.  For bug
reports use the BUGFORM.

If you have a problem with a precompiled version of Window Maker (rpm, deb etc),
first ask the person who made the package.

IMPORTANT NOTE: when asking for help (in the mailing list or to the developerts,
directly) *always* send information about the system you are using. You can use
the system information section at the end of BUGFORM as a guideline. Another
thing: please don't send HTML mail.


There is also a #windowmaker IRC channel at freenode. To join there, connect
your irc client to irc.freenode.net. irc.windowmaker.org will direct you to the
correct IRC network.


GNUstep
=======

GNUstep is a complete object-oriented development system, based on the OpenStep
specification released by NeXT(tm) (now Apple(tm)) and Sun(tm). It will provide
everything one needs to produce cross-platform, object-oriented, graphical (and
non-graphical) applications; providing among other things, base system
libraries, a high-level GUI application framework that uses a Display
PostScript(tm)-like imaging model (DGS), objects for accessing relational
databases, distributed objects and a graphical development environment, with
tools like interface modeller, a project management system (project center) and
other tools.

The GNUstep development system will be used to create a user environment, with
everything needed for a complete graphical user interface, such as a file
viewer, text editors and other applications. Note that the user environment (or
"desktop environment") is only a small part of the whole GNUstep project and
therefore it does not "compete" with other projects like KDE or GNOME, simply
because they are completely different things.

For more information on the GNUstep project, visit: http://www.gnustep.org


Running multiple instances of Window Maker
==========================================

It is not a good idea to run more than one instance of Window Maker
from the same user (so that wmaker will use the same configuration files) at the
same time. You might get unexpected behaviour when Window Maker updates it's
configuration files.

If you really desire to do this, try running Window Maker with the command line
option --static so that it will not update or change any of the configuration
files.


Performance Tuning
==================

If you want to diminish Window Maker's memory usage and improve performance,
while keeping a nice appearance and good functionality, follow the items bellow:

- use solid textures for everything, mainly titlebars and menus. If you want a
  nice looking desktop, use the Traditional style.
- turn NewStyle and Superfluous off
- do not bind many shortcuts in the menu and keep only the essential items in
  the menu
- turn on DisableClip
- edit wconfig.h and disable the NUMLOCK_HACK and the features you don't use
  anyway (keep in mind that some of the #defines might not work, as they are not
  fully supported). Make sure to always keep NumLock and ScrollLock turned off.
- turn on DisableAnimations. You can also #undefine ANIMATIONS in wconfig.h
- strip down the default IconPath and PixmapPath entries to contain only 
  the paths that you really have in your system. 
- do not use large images in the root background
- remove support for image formats you don't use
- to reduce memory usage, disable the icon cache, by setting the RIMAGE_CACHE
  environment variable to 0. If you want to increase performance at the cost of
  memory usage, set it's value to a value like the number of different icons you
  use. Also, disable anti-aliased text support in ~/GNUstep/Defaults/WMGLOBAL.


Keyboard Mouse Control
======================

Many people ask about adding keyboard control of mouse, like in fvwm, but Window
Maker will not have such feature. The XKB extension supports mouse simulation
from the keyboard, in a much more powerfull fashion than any simulation done by
a window manager.

To enable it, hit the Control+Shift+NumLock or Shift+NumLock key combination.
You should hear the speaker beeping. To disable it, do the same thing.

To control the mouse the numeric keypad is used as follows:
- 4 (left arrow), 7 (Home), 8 (up arrow), 9 (PgUp), 6 (right arrow), 
3 (PgDn), 2 (down arrow) and 1 (End) move the mouse to the corresponding
direction;
- holding one of the above keys and then holding the 5 key will move the
pointer faster;
- / will select the first mouse button (left button);
- * will select the second mouse button (middle button);
- - will select the third mouse button (right button);
- 5 will do a click with the currently selected mouse button;
- + will do a double-click with the currently selected button;
- 0 (Ins) will click and hold the currently selected button;
- . (Del) will release the currently selected button that was previously
clicked with the 0 (Ins) key.


The above key values work in a XFree86 3.2 (X11R6.1) X server but your
milleage may vary.


How to make a gdb backtrace
===========================

Backtraces can help us fix bugs that make Window Maker crash. If you find a bug
that crashes Window Maker, please send a backtrace with your bug report.

To make a usefull backtrace, you need a core file with debugging information
produced by Window Maker when it crashes. It should have been installed without
stripping too.

To compile wmaker with debugging information:

  ./configure
  make CFLAGS=-g

If you get the dialog window telling you that wmaker crashed and asks you what
to do, tell it to "Abort and leave a core file".

  script
  cd src
  gdb .libs/wmaker path_to_the_core_file

Then, in the gdb prompt type "bt". Quit from gdb by typing "quit" and then, in
the shell prompt, type "exit".

The file named typescript will contain the backtrace.
