For the license, I did put MIT, but I am not sure it's acceptable because again it's a quite obscure COPYRIGHT file (ref: T4332)

oOo

Since the original terms of 15 years ago maybe do not make our
intentions completely clear given today's refined usage of the legal
terms, we append this additional permission:
