If this is work derived from dictobject.h, you are bound by the Python
license, see the file LICENSE for details. It is
fairly strict in what you have to do, see, in particular, clause 2
of the PSF license, the BeOpen License, and the the CNRI license.

You have to include the license file itself, as well as a certain magic
incantation.
