I noticed the GNU GPL v3 license created by Github is very different than the one created by Netbeans. One of the differences is the first line in Netbean's is Copyright (C) 2016 hotwisp Must the GPL include the real name or pseudonym (e.g. username) of the copyright holder or author?How could the GPL be different between Netbeans and Github? Here is the rest of the license added by Netbeans:This program is free software: you can redistribute it and/or modify  it under the terms of the GNU General Public License as published by  the Free Software Foundation, either version 3 of the License, or  (at your option) any later version.      This program is distributed in the hope that it will be useful,   but WITHOUT ANY WARRANTY; without even the implied warranty of  MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the   GNU  General Public License for more details.      You should have received a copy of the GNU General Public License   along with this program.  If not, see http://www.gnu.org/licenses/.I would include Github's but it's over 600 lines long! Is the GPL licnece itself copyrighted? For example are you free to modify it as seen fit, and that's what Github or Netbeans did?
Must author's name be included in GNU GPL v3?
