Thank you for the help. For the moment, I will start by absorbing the
documentation. And will give an update (since I will have to try to do
this on my spare time, it will take some time) if I need help or if I
would like to use an adapted existing implementation with a problematic
(from the kerTeX license point of view) licence.

Best regards,
