       xsnow - let it snow on your desktop and windows

       xsnow [-option .,..]

       Xsnow lets it snow on your desktop and windows (sic!).

       -display display_name
	       Drop  the snowflakes on the given display. Make sure the display is nearby, so you
	       can hear them enjoy...

       -snowflakes num_snowflakes
	       This is the number of snowflakes. Default is 100, max is 1000.

       -sc snowflake_color
	       Use the given string as the color for the flakes instead of the default "snow".

       -bg background_color
	       Use the given string as the color for the background. Note that the usual  default
	       desktop	pattern  consisting of 50% white 50% black doesn't particularly look good
	       with Xsnow.

	       When using solid colored backgrounds specifying this option  MAY  greatly  improve
	       performance. (Not on SUN Solaris 2.5.1 for example!)

       -tc tree_color
	       Use the given string as the color for the trees.

       -slc sleigh_color
	       This  option  is  obsolete  in version 1.41.  Used to be the color for the sleigh.
	       Santa has decided not to have you interfere with the color of his means of  trans-
	       portation any more.

       -santa santa_size
	       There  are 3 sizes of Santa: 0, 1 and 2. Default is 2. Thanks to Thomas Linder for
	       the (big) Santa!

       -santaspeed santa_speed
	       The speed Santa should not exceed if he doesn't want to get  fined.   The  default
	       speed for Santa size 0 is 1, for Santa 1 it's 2 and for Big Santa it's 4.

       -santaupdatefactor factor
	       This is to slow down Santa with respect to the snow. Default the value is 3, mean-
	       ing that Santa is moved only every third time the  snow	flakes	move.  Specifying
	       zero here is considered very naughty.

       -delay delay
	       This is the number of milliseconds delay after updating everything.  Default is 50
	       milliseconds, i.e. 20 updates per second max.

	       If you specify this option the snowflakes will 'whirl' more dramatically,  result-
	       ing in a somewhat jerkier movement.

       -whirl  This  sets  the whirl factor, i.e. the maximum adjustment of the horizontal speed.
	       The default value is 4.

       -nowind Default it gets windy now and then. If you prefer it quiet specify -nowind.

       -windtimer period
	       With -windtimer you can specify how often it gets windy. It's sort of a period  in
	       seconds, default value is 30.

       -xspeed -yspeed
	       These options set the maximum horizontal and vertical speed. The default X maximum
	       speed is 4, the default maximum Y speed is 8.

       -wsnowdepth -ssnowdepth
	       This sets the maximum thickness of the snow on top of windows and at the bottom of
	       the  display  respectively. The default snowdepth for windows is 15, at the bottom
	       of the screen the default is 50.

       -offset With -offset you can specify that snow starts building up a number of pixels lower
	       or higher. This is handy if you use twm and squeezed window titles.

	       Do not display the trees.

	       Do not display Santa Claus running all over the screen.

	       No Rudolf.

	       Do not have snow sticking anywhere.

	       Do not keep snow on top of the windows.

	       Do not keep snow at the bottom of the screen.

	       Xsnow  takes  care  to  not let it snow on Pop-up windows, due to their nature. If
	       however, you use an Xserver that has backing store on for all windows, then  spec-
	       ify  this option. Symptom would be that no snow is kept on any window, but only at
	       the screen bottom.

	       Prints the current Xsnow version and does not start Xsnow.   The  current  version
	       (of this man page) is 1.42, December 14th 2001

	       Starts xsnow

       xsnow&  (Mind  the  empersand) Starts xsnow as a background process. Use this if you start
	       xsnow from a script. To stop xsnow find	the  process  id  (pid)  as  follows:  ps
	       -ef|grep xsnow and use the kill command to stop xsnow.

       xsnow -bg SkyBlue3 -sc snow
	       Sets the background to a bluish color and lets it snow white.

       xsnow -ssnowdepth 100
	       Starts  with  a	thin  layer of snow that gradually builds up at the bottom of the

       xsnow -santa 2 -santaspeed 10
	       Gives you the biggest Santa at a speed that is hardly legal.

       xsnow -delay 100 -notrees
	       For slow systems use longer delay and don't draw the trees.

       xsnow -snowflakes 1000 -delay 0
	       Uses the maximum number of snowflakes and runs as fast as possible.

       xsnow -bg SkyBlue3 -solidbg
	       Sets the background to a bluish color and specify -solidbg for  increased  perfor-
	       mance (depending on your system!).

       See  /usr/lib/X11/rgb.txt  for  the list of colors and their respective poetic names, like
       Chartreuse and SkyBlue3.

       Xsnow is available freely and you may give it to other people as  is,  but  I  retain  all
       rights.	Therefore  it  does  not  classify  as 'Public Domain' software. However, it *is*
       allowed to package Xsnow for Unix/Linux distributions, CD-Roms etc, and to make the neces-
       sary changes to makefiles etc. to facilitate this.

       Xsnow borrows some code from xroach by J.T. Anderson (jta@locus.com)

       Xsnow  uses  vroot.h  for  use with virtual window managers.  vroot.h is copyright 1991 by
       Andreas Stolcke, copyright 1990 by Solbourne Computer Inc. (stolcke@ICSI.Berkeley.EDU)

       The big Santa was made by Thomas Linder (Thomas.Linder@gmx.net)

       The  idea  and  code   for   wind   are	 from	Eiichi	 TAZOE	 (tazoe@yamato.ibm.co.jp,

       Xsnow  1.42  works  with KDE, thanks to Robin Hogan <R.J.Hogan@reading.ac.uk>, who figured
       this out for xpenguins 2.2

       System load
       Xsnow itself doen't use very much CPU time, but it can load the X  server  and/or  network
       quite  substantially.  Use  less snowflakes and a bigger delay in such a case. On a stand-
       alone workstation there usually will not be be any problem. Another improvement can be  to
       specify	a solid background color with -bg and with this also specify the option -solidbg.
       This may greatly improve performance! DO check this though, on some systems  (SUN  Solaris
       2.5.1) performance is much WORSE.

       KDE (etc)
       Xsnow now works with KDE, and some other root window occupying desktop management systems.
       On KDE your icons will be snowed away magnificently, although that is not harmful for your
       icons really. Simply wipe with a small window where you thought your trash was, and see it
       appear.	Now you need to scrape your computer screen too, not just your car's.

       SGI Irix 5.x
       Silicon Graphics and Irix 5.x users may not see any snow or Santa  at  all,  as	long  the
       desktop icons are visible. To circumvent this problem issue this command:

	 /usr/lib/desktop/telldesktop quit

       The  icons will disappear and Xsnow will work perfectly. To restart the desktop just start
       /usr/lib/desktop/startdesktop or select Desktop->Home Directory from the toolchest.

       It's even possible to have both - desktop icons and xsnow (and even multiple  desks).  You
       need  to  modify  the  window  manager's  resource  file  4DWm, the file ~/.desktop-`host-
       name`/4DWm. Example:

       *Global.backgroundDescription:	-execute /etc/killall -TERM xsnow ; /usr/local/bin/xsnow
       *Desk 1.backgroundDescription:	-execute /etc/killall -TERM xsnow ; /usr/local/bin/xsnow
       *Desk 2.backgroundDescription:	-execute /etc/killall -TERM xsnow ; /usr/local/bin/xsnow

       Restart the window manager (4Dwm) from the toolchest and Xsnow should  appear.  What  this
       does  is  stop  the currently running Xsnow and start a new one when you switch to another

       HP and hp-ux
       HP also uses a Workspace Manager which may  interfere  with  Xsnow.   If  Xsnow	does  not
       appear: In the "Style Manager", choose "Backdrop" and select "NoBackdrop".  You should now
       be able to run Xsnow.

       Snow does not stick?
       On black-and-white X terminals snow may not stick to windows because backing store is  on.
       Try specifying the option -nonopopup when starting Xsnow.

       Snow hovering above windows?
       If you use twm it is possible you see the snow layer hovering a little bit above your win-
       dows. In that case set BorderWidth 0  in  your  .twmrc  file.  If  you  use  windows  with
       'squeezed title bars' specify a -offset to get the snow on the windows itself.
