Hi,
I was talking today with Simon about the "License cleanup" changes. He would prefer when the *.license files don't exist (when possible). Luckily, I already wanted to convert these files (or at least the READMEs) to reStructuredText and I've already shown in these patchsets how the SPDX annotation should be done for the lrest files. So it was just logically to immediately post the conversion to rst and integration of this tag.
We've also discussed how the changelog should look like. It should be simple and we only wanted to show the date (not the time) anymore. And the actual changelog lists should be kept (mostly untouched - beside some minor format fixes to make it reStructuredText compatible).
This patchset is based on the "alfred: License cleanup" patchset.
Kind regards, Sven Sven Eckelmann (2): alfred: Convert CHANGELOG to reStructuredText alfred: Convert README to reStructuredText

The current format of the file is not well defined. The reStructuredText format (as used by other batman-adv related files) has the benefit that it is similar easy to read and write. And it allows other tools to parse the content of the file and convert it in a sensible way to a different file format.
Multiple git repository web-based management software also can directly render these files as properly formatted HTML output.
