Hi!
While conducting a research in the spirit of the "reproducible builds" [1], we have noticed that the package screenkey could not be built reproducibly, in that the python interpreter introduces non-determinism when generating the bytecode (.pyc file, see the attached diff.json). According to the documentation [2], invoking "export PYTHONHASHSEED=0" before the bytecode compiling will solve this issue. The attached patch does exactly this. Once applied, the package can be built reproducibly. Additional info: * screenkey 1.4-1 Steps to reproduce: The unreproducible build result could be detected with reprotest [2].
