Hi Anup,
It doesn't look like Fedora provides that package. Also, is the source
for the packages of those other distros maintained? If I found the
correct source, then it's [1], which hasn't had any attention in five
years, even though there have been hundreds of commits to Linux's
scripts/kconfig. I wonder if we shouldn't consider adopting
scripts/minikconf.py from the QEMU sources and sticking to the kconfig
language subset that parser supports?

Thanks,
