From what you quoted I agree that it seems its reference to MIT license is historical only, and the actual license of that file is GPL. Even if it was listed as both GPL and Expat licensed (and *not* explicitly listed as a choice of _either_ of them) then effectively the license would be GPL and we would not need to list the Expat license in copyright file (as long as we preserve the headers in the source and list the copyright holders). If skipping formal mention of Expat in copyright file License field, then it is probably a good idea to mention it casually in related Comment field to indicate that the omission was done after deliberate reflection, not accidentally (e.g. after using an automated and too sloppy license scanner). - Jonas -- * Jonas Smedegaard - idealist & Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ [x] quote me freely [ ] ask before reusing [ ] keep private
