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 screencast:

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

REUSE Features:

• SPDX copyright and license comment headers for all relevant files (please be aware that to serve as example I only added header to the files in the rsc directory, in the case that you want to implement the REUSE specifications we kindly ask you to add the headers to the rest of the files following the example)

• LICENSES directory in the root of the project with the licenses used on the repository (I included in this directory the file that contained the AGPLv3 license text named as COPYING and changed its name for the name of the license).

• Associating Copyright/ Licensing information through a DEP5 file in large image directories (In large image directories, like yours, where including a comment header for each image file is impossible or undesirable, you may display copyright and licensing information in a DEP5 file)

Files missing copyright and licensing information:

I added the comment headers with copyright and license information to some of the files that lacked that information in the rsc directory.

I provided a more detailed license information to README file as well

Please also double check if the personal information in the headers is correct and consistent, in the case of several copyright holders please update that information in the headers.

No contribution policy:

We have noticed that your project does not have a contribution policy. Therefore, we strongly recommend you to implement one. 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!
