The IJG convention is to format copyright notices as: Copyright (C) YYYY, Owner. We try to maintain this convention for any code that is part of the libjpeg API library (with the exception of preserving the copyright notices from Cendio's code verbatim, since those predate libjpeg-turbo.) Note that the phrase "All Rights Reserved" is no longer necessary, since all Buenos Aires Convention signatories signed onto the Berne Convention in 2000. However, our convention is to retain this phrase for any files that have a self-contained copyright header but to leave it off of any files that refer to another file for conditions of distribution and use. For instance, all of the non-SIMD files in the libjpeg API library refer to README.ijg, and the copyright message in that file contains "All Rights Reserved", so it is unnecessary to add it to the individual files. The TurboJPEG code retains my preferred formatting convention for copyright notices, which is based on that of VirtualGL (where the TurboJPEG API originated.)
