--AHI is available for personal use without any charges. I strongly believe in free software, and I use free high-quality software tools daily. But I live, like all of us, in a real world. As a student, my income doesn't even suffice for the rent, and much less food, course literature and entertainments. Therefore I ask, if you like this software, please consider showing your gratitude by making a small donation (see section The Author for my address).
