The program I want to add to my repository is MIT licensed in this case, but if possible I'd like to get an answer not specific to this license. My question is basically: /what is the conventional and correct way to make note of his license such that I can just take the file and put it in my repo? I know his license allows for it but I'm not sure what I should do. (I could copy his file, but what would be 'correct' way to note to which files it applies?)
An extra difficulty here is that it concerns brainfuck code, in which there are no normal comments. So I can't just take the license and put it at the top of the copied file either, which is what I would do otherwise.
