Hello all! Thanks for all the great work you do. I was browsing the GNU Autoconf repo and became rather confused about what the license is for GNU Autoconf. File copyright headers say that the project is licensed under GPLv3+. However, the project website (http://savannah.gnu.org/projects/autoconf) says that it's licensed under GPLv2+. I'm inclined to believe the copyright headers, but the main COPYING file is GPLv2. Is this significant? Thanks, Jack
