NAME
       xsnow - let it snow on your desktop and windows

SYNOPSIS
       xsnow [-option .,..]

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

OPTIONS
       -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.

       -solidbg
               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               This option is obsolete in version 1.41.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 transportation 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, meaning 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.

       -unsmooth
               If you specify this option the snowflakes will 'whirl' more
               dramatically, resulting 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.

       -notrees
               Do not display the trees.

       -nosanta
               Do not display Santa Claus running all over the screen.

       -norudolf
               No Rudolf.

       -nokeepsnow
               Do not have snow sticking anywhere.

       -nokeepsnowonwindows
               Do not keep snow on top of the windows.

       -nokeepsnowonscreen
               Do not keep snow at the bottom of the screen.

       -nonopopup
               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 specify this option. Symptom
               would be that no snow is kept on any window, but only at the
               screen bottom.

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

EXAMPLES
       xsnow
               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 screen.

       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 performance (depending on your system!).

FILES
       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 necessary
       changes to makefiles etc. to facilitate this.


CREDITS
       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

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

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


NOTES
       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 standalone 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-`hostname`/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 desktop.

       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 windows. 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.
