Though CLHEP is released under GPL-3 and LGPL-3 dual licenses since, the Matrix sub-library of CLHEP still has an anti-commercial
clause in its license, e.g.,

  /* Matrix/Matrix/Matrix.h */

  // Creation of derivative forms of this software for commercial
  // utilization may be subject to restriction; written permission may be
  // obtained from Cornell University.

and I failed to convince the upstream to remove this clause. If we
purge the Matrix sub-library to make CLHEP DFSG clean, it will be
useless for Geant4.

(Maybe we can upload it to non-free?)

Kind regards,
