This is a program to learn Japanese written by someone who does not even speak Japanese. So, beware. I've tried to be accurate, seeing as I'm using writing this program to learn Japanese, but as it hasn't even been looked over by a fluent speaker, I can't guarantee it.

Technical info: Keolah Learns Japanese was created with the Eclipse IDE, the MinGW compiler, and the Allegro graphics engine. Text files were edited with NoteTab Lite. My computer is running Windows XP. This project was fueled by ramen noodles.
Legal crap: Right, this is supposed to be the section where I go into a bunch of licensing mumbo-jumbo, isn't it? I'm not going to bother. I don't care what you do with my code. I made this for fun, and I'm not going to start throwing around words like copyright or copyleft or anything else. Let's just call it public domain. Do what you want with anything I wrote. You don't have to ask permission, notify me, or even credit me. I don't care. Have fun.
