Dear Maintainer,
While working on the “reproducible builds” effort [1], we have noticed
that 'cython' could not be built reproducibly.
The attached patch uses debian changelog last entry's year as copyright
year in the documentation (through SOURCE_DATE_EPOCH). Once applied,
cython can be built reproducibly in our current experimental framework.
Regards,
Alexis Bienvenüe.
