How to generate a license?

Question

Licenses for software and other works

There is a GPL license, and Wikipedia even has a section on how to write it. But still, I’m bad with English in order to write according to the scheme, but are there any templates just to substitute my necessary data?
For example, CodeIgniter's license has been merged into one common text! Although CodeIgniter is licensed under the CodeIgniter License Agreement, not the GPL. Is it somehow fundamental?

Answer 1

There is a template for putting in the name of the program and your name, and it is found at the end of the GNU GPL itself , in the "How to Apply These Terms to Your New Programs" section. But if you want, I can quote him:

<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year>  <name of author>

You should have received a copy of the GNU General Public License
along with this program.  If not, see <http://www.gnu.org/licenses/>.

It must be added to the beginning of each source code file. Also, in the root of the project, you need to put the full text of the license ( here it is in plain text ) under the name, as a rule, COPYING.
If your program has an interface, then you should make sure that, in addition to the author's name, the full text of the license is also available from it (for example, through the "About" window).
That's all, nothing complicated.
