I wasn't insulting his program, I hadn't even tried it or seen it. I read through the thread and saw the discussion and thought it was a bad thread, not because of the program, but because of the interaction between Gunderak and the people posting in the thread. Especially on the page where people were talking about the gani format.. It's a plaintext format. It's not like you have to reverse engineer a binary format. It's really simple.
Anyway, Gunderak has a very poor track record among the veteran scripters of Graal, so it's not unreasonable to be prejudiced. In fact, it makes sense to be prejudiced.
