All you see, the software, the documentation, the website, need a huge effort. Thousands hours, no joke.
I do it because i like it, but if you want to offer me a beer or pizza, I'm pleased.
If you can't send me the pizza, consider sending me the money and I will buy it myself. ;-)
At the moment i don't know how to put the paypal button on this wiki, so just go to the homepage and you find it there.
