These were made with a very old version of Gregorio...
* \includescore command is defined in gregoriotex.tex which is GPLv3
* 'rougeliturgique' isn't useful anymore as you just need to use the
<c> tag in your gabc code and you can use \grecolored if you want to
use that color somewhere else
* you can find most formatting options in
https://github.com/gregorio-project/gregorio/blob/master/examples/main-lualatex.tex
which is also GPLv3
* \hss is a standard TeX command... and thus Public Domain

That said, I don't think GPLv3 is the right license for content as
it's really meant for software. And the little programming one would
include in a TeX document doesn't make it a software...

Yours,

Olivier
