       FvwmBacker - the FVWM background changer module


       FvwmBacker is spawned by fvwm, so no command line invocation will work.


       The  FvwmBacker  module  provides  functionality  to  change  the background when changing
       desktops.  Any command can be executed to change the backgrounds.  The  commands  used  to
       change  the backgrounds must exit after changing the root window, (i.e. 'xv -root zzz.gif'
       does not, without the -quit option) otherwise FvwmBacker will hang.


       The FvwmBacker module is the original work of Mike Finger.

       Copyright 1994, Mike Finger. The author makes no guarantees  or  warranties  of  any  kind
       about the use of this module.  Use this modules at your own risk.  You may freely use this
       module or any portion of it for any purpose as long as the copyright is kept intact.


       During initialization, FvwmBacker will scan the same configuration  file  that  FVWM  used
       during  startup  to find the options that pertain to it.  These options are discussed in a
       later section.


       FvwmBacker can be invoked by fvwm during initialization  by  inserting  the  line  'Module
       FvwmBacker' in the .fvwmrc file.

       FvwmBacker  must reside in a directory that is listed in the ModulePath option of FVWM for
       it to be executed by FVWM.


       The follow option is the only only support at present

       *FvwmWinListDesk DeskNumber command
              Specifies the command to execute when the specified DeskNumber becomes active.

              If the command begins with -solid FvwmBacker uses the next argument as a  color  in
              the  X  database  and sets the background to that color without generating a system
              call to xsetroot. Only single word color names may be used.


       The following are excepts from a .fvwmrc file  which  describe  FvwmBacker  initialization

       # Set Up Backgrounds for different desktops.
       *FvwmBackerDesk 0 -solid steelblue
       *FvwmBackerDesk 1 -solid midnightblue
       *FvwmBackerDesk 2 -solid yellow
       *FvwmBackerDesk 3 xpmroot /usr/include/X11/pixmaps/background2.xpm
