Thanks!

I realized that I haven't answered to your questions on the MMG5_ prefixes.
This warning is very probably obsolete.

I initially used the MMG5 prefix because the first Mmg repository contained only mmg3d but 2 versions of it: the V4 that was already used by some partners and the V5 by others. When I created the APIs for the V5, I wanted to ensure the differentiation between the 2 versions (I think that the V4 didn't have true APIs).

Finally, we remove the sources of Mmg-4 and add the sources of Mmg2D and MmgS. As the 3 software provides the same kind of functions, it raises the need for other API prefixes without breaking the previous one and all 3D APIs functions whith MMG5_ prefix have been duplicated with the MMG3D_ one.

Now everything has been cleaned:

• data structures and parameters that are common between the 3 software uses the MMG5_ prefix.
• API functions should have a MMG< 3D | 2D | S > depending on the software
• some MMG5_ API functions exists but they are common to the 3 software (the 3D MMG5 APIs have been removed)

I am still not sure if having the major release version in the API prefix is a good idea: on one side, it will force the users to update their Mmg interfacing if we release a new major version. On the other side, it is very likely that a new major version will break the current API and that it will be the occasion to improve a lot this API and to change things that I would do differently with hindsight.
