"   We decided to distribute all of our aa-related programs freely (see \n"

"It is extremly useful in combination of lynx-the best web browser. \n"

"at a boot time as a logo on our secondary monitors. There was a small problem \n"
"- Hercules doesn't support color graphics. So we decided to convert an image \n"
"to ascii art using netpbm tools.\n"
"\n"
"The output was very ugly because the converting algorithm was absolutly stupid. \n"
"During the night I designed a new convertor that used a font bitmap for \n"
"creating aproximation table. The output wasn't very good since the algorithm \n"
"wasn't so well tuned. Many months this small piece of code was waiting on my \n"
"disc for the day \"D\". Meanwhile I started a new project XaoS (a fractal zoomer) \n"
"with my friend Thomas. And then I got an idea: Ascii Art Mandelbrots! \n"
