If an open source software licence requires to "preserve this notice", which usually appears within the source code file, and I'm not distributing any parts of the source code (but only binary files), does that mean that I don't have to do anything with that original licence? Or would I have to create a new file with that licence notice, or include it into some documentation or even let the application reproduce the licence notice on the screen?
Does it matter whether the original licence was embedded in the source files or distributed as a separate file?
I'm thinking about shorter licences like BSD or MIT, or even those called "public domain". AFAIK the GPL or LGPL require distributing the separate licence text file as it's quite lenghty. I don't know about other licences like Apache or CC.
