This is a simple program to change the background periodically.

It takes one or more directories with images as a parameter (no GUI) and sets a 
randomly chosen image as background. If there is a border remaining, its
color is the average color of two corners of the image. This mostly fits the 
image very well.

It is also possible to execute a command when the image changes. This could be 
used for things like calling a program that announces your new background-image 
on IRC. But please don't do *that*. ;)

Read the manpage for usage instructions.
If you don't want to "make install" the program, "man zufall" will not work.
In this case you can
- read the manpage with less if you are lucky: less zufall.1
- try to read the manpage directly with groff:
  groff -S -s -p -t -e -Tascii -mandoc zufall.1 | less
- read the online-version at http://apfelboymchen/nett/gnu/C/zufall/zufall.1.html
