I searched for this question over the internet but with no success.
I got a MIT licensed python library and did my modifications to fit my necessities. I want this new version to be a copyright with all rights reserved. I know that even if I don't say anything, this new project is automatically under all rights reserved to me. Even so, I want to add some note that indicates the copyright, as the same way the MIT License note previously added in the original project.
The most common practice for licencing is adding a
LICENSE file to the root dir with the license text. For sub-license as a "all rights reserved", what is the main procedure or the common procedure? How, in practice, can I do it?
