NGI0 - Updating licensing aspects according REUSE

[lnceballosz]

Hello,

We have been working within the NGI0 framework, helping projects with their licensing and copyright management. After a quick check on your repository, I would like to propose some updates regarding copyright and licensing information. REUSE specifications intend to make licensing easier by setting one way to display all this legal information through comment headers on source files that can be human - and machine – readable.

The REUSE tool makes the process of applying licenses to files and compliance checking much easier. Check this screen-cast:

Feel completely free to adopt these specifications by merging this pull request.

REUSE Features:

• SPDX copyright and license comment headers for all relevant files (first of all let me thank you for implementing such a good practice as displaying license and copyright information in individual files. I just added the REUSE specification to all of them).

• LICENSES directory in the root of the project with the license used on the repository (Please notice that I added the AGPL-3.0-only text)

Files missing copyright and licensing information:

I added the comment headers with copyright and license information to all the copyrightable files. I noticed that most of the files had a correct copyright and license information. However, as good practice, I just added the consistent headers with the REUSE specifications.

I provided a more detailed licensing information to README file as well.

Please also double check if the personal information in the headers is correct and consistent.

No contribution policy:

We could not find a very solid contribution policy in your project. Therefore, we strongly recommend you to improve it or create it. To get further information about this please check our documentation: https://download.fsfe.org/NGI0/V2/FSFE%20-%204%20-%20Free%20Software%20Contribution%20Policy.pdf

Further REUSE compliance

In case you find REUSE useful, we offer a wide range of tools to help you to continuously check and display compliance with the REUSE guidelines.

Hope that helps and thank you very much for the amazing job!
