Well BSD says that license should be included with the sources, but
does not force you to sprinkle copy of the license to multiple
places.  I _think_ that legaly NAG notices in separate files
could be replaced by a single one, but since NAG wanted per file
licence I keep it that way.  Similarly with other licences.

As I wrote you most of old stuff that you bundled never was part of
FriCAS repository.  New contributions, are covered by overall
LICENSE.txt.  Concerning Arthur Ralfs, I do not know why did you
put separate licence file in Axiom.  Artur knew Axiom and FriCAS
licence, clearly wanted his code to be included and I included
what he provided.  Did he request you to put this licence file?
