Yah, the -f thing is almost mandatory. I can imagine simply downloading
the latest cpuid.leafs or so and then running kcpuid on it. Can't get
any better than this I'd say.
Which reminds me: we probably should aim at not changing that text
file's format too often and design it to contain the required info
from the get-go so that we don't have uglies with old kcpuid not
understanding the new format or the other way around. That would be a
pain.
