PURPOSE

   RandomBG is a very simple program to randomly select  a  file  from  a  given
   directory  and  set  it  as  either  workbench,  window  or screen background
   picture. RandomBG doesn't make any changes on your harddisk, it just  updates
   the  file  "ENV:sys/WBPattern.prefs" in RAM and makes the IPrefs process load
   the new selected pictures.

   RandomBG will scan these directories, randomly  select  one  file  from  each
   directory and then set the new backgrounds.


SYNOPSIS

   WBDIR,WINDIR,SCRDIR,VERBOSE/S


INPUTS

   WBDIR, WINDIR and SCRDIR are the directories where you keep your background
   pictures. RandomBG is able to select a picture for each background type from
   a different directory.
   If you for example just give the directory WINDIR, then  RandomBG  will  just
   update  the  background  picture  for  windows  and  leave the background for
   workbench and screen as it is.
   Enabling the VERBOSE option will make RandomBG output  a  few  things  it  is
   currently doing.


RESULTS

   The workbench, window and screen background  picture  will  be  automatically
   updated by the IPrefs process.


EXAMPLE

   RandomBG wbdir=work:patterns/workbench scrdir=data:graphic/screens

   This will select one picture for the Workbench from "work:patterns/workbench"
   and  one from "data:graphic/screens" for the screen and will leave the window
   pattern untouched.


   RandomBG windir=Work:Patterns/Window verbose

   This  will  just  select  a  new  window  background  from   the   files   in
   "work:patterns/window" and additionally output something like this:

      choosing workbench background
      choosing window background
        old file: Work:Patterns/Window/bd3.png
        new file: Work:Patterns/Window/Sand.png
      choosing screen background

   Workbench and screen background are left untouched.


BUGS

   Hopefully none.


HISTORY

   V1.2: - fixed endless loop when there was only one or no picture in one of
           the directories
