I don't much like boilerplate. : : I'd greatly prefer not to. You can refer to a COPYING and we can have a : default COPYING file but a copyright is really needed as far as I : understand it. The copyright exists regardless of any notices being on the file. In the absence of a license to copy, however, the default legally defined license is 'you may not copy it at all'. Based on this, you need to have an explicit license for all files. However, it only needs to be clear what the license for a given file is. You don't have to have the license in each and every file.
