Bug#745289: License of objsize

[Dmitry Grebeniuk <gdsfh1@gmail.com>]

Hello.

  As an original author of objsize, I'll clarify license:

  Dual: BSD (3-clause) / GPL.

  Next release of objsize will have this statement in
README file.

  If somebody feels uncomfortable with this license,
mail me and we'll discuss it (and change it, probably).
