gpl: Show the GNU General Public License notice
gpl command displays the license notice for the latest version of the GNU General Public License. Options --v1, --v2, and --v3 control which version of the license is shown.
To display the full license text instead of just the license notice, use the --full option.
The --jerkwad option removes the Or any later version clause from the license notice.
This command downloads the license from www.gnu.org/licenses/gpl.txt.
The address options --address-link, --address-franklin, --address-temple, and --address-mass are used to modify the final paragraph of the license notice to point to the website, the current address, or an old address of the Free Software Foundation. The old addresses are added for license notice matching on old source files which may not have updated their addresses.
