Hi Tilman, Gautier,

Thanks for your input! I'll think about the best course of action given these options.

Hello Ewoud,

Although the current license is not compatible with MIT, the two main
files containing the INDI code are written by you and corrected
sometimes by Freek or students from TUDelft. So in practice, you could
decide to change the license for the files your are concerned.

If you decide to do it, I would recommend to choose the LGPL, which
keeps a bit more the "hard" opening of the original license and would be
compatible with MIT as non-contaminating.

Note that this won't apply to the math library we are using so they will
have to rewrite a few things anyway. In my opinion, they should look at
our code for some hint in implementation and write their own using their
preferred libraries, it is not that long.
