Ice Window Manager (IceWM)
==========================

This is a fork of the IceWM CVS on [sourceforge][13].  It includes all changes
from the `icewm-1-3-BRANCH` branch, greatly enhanced EWMH/ICCCM compliance, as
well as patches collected from Arch Linux, Debian, pld-linux, the IceWM bug
list, and various other GitHub forks.

> is much more important than 'Look' ...


Release
-------

This is the icewm-1.3.12.56 package, released under LGPL license 2016-07-08.
This release as well as future versions here, can all be obtained from
[GitHub][1] using a command such as:

    git clone https://github.com/bbidulock/icewm.git

When working from `git(1)`, please use this file.  An abbreviated
installation procedure that works for most applications appears below.


Quick Start
-----------

The quickest and easiest way to get IceWM up and running is to run the
following commands:

    $> git clone http://github.com/bbidulock/icewm.git
    $> cd icewm
    $> ./autogen.sh
    $> ./configure --prefix=/usr --sysconfdir=/etc \
       --enable-shaped-decorations --enable-gradients \
       --enable-guievents --with-icesound=ALSA,OSS \
       --disable-menus-gnome2
    $> make V=0
    $> sudo make DESTDIR="$pkgdir" install

This will configure, compile and install IceWM the quickest.  For those who
would like to customize the installation, use the command:

    ./configure --help

Please see the [INSTALL][3] file for more detailed installation instructions.
The [ChangeLog][4] file contains a detailed history of implementation changes.
The [COMPLIANCE][5] file lists the current state of EWMH/ICCCM compliance.  The
[NEWS][6] file has release notes and history of user visible changes of the
current version.  The [TODO][7] file lists features not yet implemented and
other outstanding items.

This release is published under LGPL license that can be found in the file
[COPYING][8].


Configuring IceWM
-----------------

Documentation for configuring the window manager can be obtained from [IceWM
Website][14] or from the online manual: point your browser at [this file][16].

Unfortunately the documentation is for version 1.2.27 and is incomplete
at that; however, it is for the most part usable.  Also, a rather sparse
`icewm(1)` manual page is available.


Included Utilities
------------------

Currently, the only included utilities are:

 - `icewmbg` (_a background setting program_),
 - `icewmtray` (_a system tray for the IceWM taskbar_), and,
 - `icewm-session` (_a program to launch the window manager, icewmbg and
   icewmtray in an orderly fashion_).


Third-party Utilities
---------------------

Unspecified keyboard shortcuts can be handled with the `bbkeys(1)` utility
available from [sourceforge][17].  For additional utilities see the [IceWM
FAQ][15].


wm-session
----------

`/proc/wm-session` is used to register the process id of an application able to
free resources smoothly when the kernel decides that memory resource have
reached a critical limit. The registered application is notified of this
situation by the signal `SIGUSR1`.

On full featured desktop machines it would make sense to use the session
manager for this purpose. On X window PDAs which have limited memory resources
it makes sense to let the window manager send `WM_DELETE_WINDOW` message to the
last recently used application.


__Requirements to uses this feature in IceWM:__

  - A patched kernel, a patch for Linux 2.4.3 is available in the contrib
    file module.

  - A patched X server assigning the clients process id to each newly
    mapped window. Alternatively you can preload the preice library
    available in the contrib file module.

  - `$ export LD_PRELOAD=$PATH_TO/libpreice.so`

  - IceWM configured to have wm-session support
    (./configure --enable-wm-session ...)

The contrib file module of IceWM is located on [sourceforge][12].
