Hi Pat,

Indeed, that seems to be the case (learn something new every day!)

At which point we could write all the verbose output to stderr and still
have it written to the console by default, with only the package name
written to stdout, and

# yum install $(nvidia-detect)

would only parse the package name as desired.

So at which point do we still need a terse option given that
nvidia-detect 2> /dev/null would achieve the same result?
