<para>&kfract; is a generator for
<ulink url="http://hypertextbook.com/chaos/"> fractals</ulink>. Well, at this
 early stage it's
only capable of mandelbrot sets and julia sets, nothing fancy like Xfractint,
and it's way far from being as fast as
<ulink url="http://spanky.triumf.ca/www/fractint/fractint.html">
 fractint</ulink>.
But it's much easier to use.</para>

<para>You can zoom in by holding the &LMB; down and drawing a rectangle to
define which part of the picture you want to zoom in to. The center of the
rectangle will be the center of the new picture, the X/Y ratio will be adapted
to fit into the window.</para>

<para>You can also zoom in by just clicking the &MMB; where you want the center
of the new picture to be. </para>

<para>Or you can zoom out by clicking with the &RMB;.</para>
