NAME
     realxfishdb, fish_props - Display a  fishtank  on  the  root
     window of an X11 server.

SYNOPSIS
     realxfishdb [ -fnn ] [ -bn ] [ -rn.n ] [ -in.n ] [ -d ] [ -s
     ]

     fish_props

DESCRIPTION
     realxfishdb displays a fishtank on the root window  complete
     with  swimming  fish  and bubbles, all in living color. This
     demo runs on Open Windows X11/NeWS  servers  v2  and  newer.
     Currently only 8 bit color is supported. The fish_props pro-
     gram allows the user to preset various  options  for  realx-
     fishdb.

OPTIONS
     -fnn The number of fish. The default is 2.  This  option  is
          ignored  if you have used the fish properties sheet and
          a ~/.fishrc file can be found.

     -bn  The number of bubbles. The suggested number is 0  since
          they  take  a  significant  amount  of  CPU  power. The
          default is 0.

     -rn.n
          Fractions of a second between refresh  updates.  On  an
          SS1  with  about  8 fish and no hardware multibuffering
          support, setting this to  0.3  leaves  you  enough  CPU
          power  to continue to edit or read mail. Default is 1.0
          (which corresponds to 100 on the property sheet).  This
          option  is ignored if you have used the fish properties
          sheet and a ~/.fishrc file can be found.

     -in.n
          Maximum fish increment. For  those  who  like  smoothly
          moving fish, set this value to a low value such as 0.2.
          The default is 1.0 (which corresponds  to  100  on  the
          property  sheet).  This  option  is ignored if you have
          used the fish properties sheet and a ~/.fishrc file can
          be found.

     -d   Use the X11 Multibuffering Extension in OWv3 and  newer
          Open  Windows  servers.  This is not recommended unless
          you have hardware support for multibuffering  since  it
          further  drains  memory  and  CPU power. The default is
          off. This option is ignored if you have used  the  fish
          properties sheet and a ~/.fishrc file can be found.

     -s   Secure mode. The default is off. This mode  covers  all
          windows  on  the screen and runs in a secure mode. Win-
          dows can't even be popped up to  stop  the  program  in
          this mode.

     fish_props is a fish properties sheet which allows the  user
     to  select  the  fish used in the program, the display mode,
     the refresh rate, and the maximum fish increment. After mak-
     ing  selections press the apply button to save selections in
     the ~/.fishrc file.  realxfishdb attempts to read this  file
     when it starts.

ENVIRONMENT
     There are image files in the  $OPENWINHOME/share/images/fish
     directory which are required to run realxfishdb.

     FISHHOME       Indicates an alternate  path  for  fish_props
                    and  realxfishdb to search for the fish files
                    otherwise if  they  can't  be  found  in  the
                    $OPENWINHOME   directory   the   final   path
                    attempted is the ./fish directory relative to
                    where the executable lives.

FILES
     $HOME/.fishrc       Contains  the  options  set  by  running
                         fish_props. realxfishdb attempts to read
                         this file upon startup.
     $OPENWINHOME/share/images/fish/*.im8
                         Image files necessary to run  fish_props
                         and realxfishdb.

NOTES
     Be patient when starting this program, it processes a lot of
     pixels  before starting up. Also, it runs on the root window
     so don't be alarmed when windows temporarily disappear.

     If you would like your very  own  copy  you  will  need  the
     fish_props  and  realxfishdb  executables  and all the files
     from the ./fish subdirectory.

     This is an adaptation of an existing X11 application  called
     xaqua of unknown origin.

BUGS
     Both fish_props and realxfishdb  dump  core  if  the  ./fish
     directory does not contain the required image files.


     The OpenWindows environment may no longer be supported in  a
     future  release.  You may want to migrate to CDE, the Common
     Desktop Environment.
