Summary: Convert JSON from newer Nvidia driver to an older one
Requires: /usr/bin/php
%description legacy-converter
Old Nvidia drivers do not have a JSON with supported models,
but JSONs of newer drivers specify GPUs supported by older drivers.
This scripts takes a JSON from a newer driver and converts it
into a JSON for an older driver which does not ship a native JSON.
