People, I forgot to tell ashark the primary reason why I felt a thread in arch general ML was needed. Almost every file in libdrm tree has it's own copyright notice, I've listed 4 examples at the bottom of the mail. The COPYING file we include with libdrm doesn't list any of those 4 notices and I have no idea how many more we miss. Are there tools to extract multiple license texts from multiple files in multiple folders, should maintainers create something by hand or are there other/better options ? How can we be sure we're not missing one or two copyright notices ? This could potentially affect many archlinux packages with numerous license types. (Wiki suggests named copyright notices are needed for BSD , ISC, MIT , zlib/png and Python licenses) Lone_Wolf Android.mk # # Copyright © 2011-2012 Intel Corporation # util_double_list.h * Copyright 2006 Tungsten Graphics, Inc., Bismarck, ND.
