EXAMPLES

       If your machine is very slow, try
       > xfireworks -fine 75 -after-image 75

       If your machine has less colors, try
       > xfireworks -gradation 5
       XFireworks use 5x5x5=125 colors.

       If you have very high spec machine, try
       > xfireworks -fine 200 -after-image 150 -gradation 64 -wait 10000

       If you like simple fireworks (it's Japanese "Wabi Sabi"), try
       > xfireworks -probability 50

       If you like loud fireworks, try
       > xfireworks -probability 500 -after-image 200 -next-number 120

       If xfireworks don't run properly, try
       > xfireworks -direct-draw
       or
       > xfireworks -no-direct-draw

       XFireworks search the configuration file in the current directry at first.  If not  exist,
       second,  XFireworks search "<XRoot>/lib/X11/XFireworks".  If not exist, XFireworks use the
       default data in itself at last.

       xfireworks.conf has more kinds of fireworks and is more beautiful.

Q AND A

       Q.
       All of fireworks are white.

       A.
       Your  machine have less colors. Use -gradation option and decrease the number of colors to
       use.

       Q.
       If I use gmc (GNOME file manager), xfireworks runs very slow.

       A.
       Try -no-direct-draw option.

       Q.
       I want to put fireworks on the root window as  a  background  picture.   But,  if  I  stop
       xfireworks with Ctrl-C, the root window is cleaned.

       A.
       Try  -no-direct-draw option. If you run xfireworks with -no-direct-draw option, xfireworks
       don't clean the root window when you stop xfireworks.

       Q.
       If I use xfireworks with -fine 500 -after-image 500 options, movements  of  fireworks  are
       not smoothly.

       A.
       Try  -no-direct-draw option. If you run xfireworks with -no-direct-draw option, xfireworks
       draw fireworks on a pixmap and copy it to the root window, and movements of fireworks  are
       smoothly.

       Q.
       I want to see more beautiful fireworks!

       A.
       Access the XFireworks's web page and download the newest xfireworks.conf.

       Q.
       I want to make my original fireworks!

       A.
       Edit xfireworks.conf. If you make more beautiful fireworks, please send it to the author.
