Dependents
We might be curious about how many programs are using <package> as a direct dependency. It turns out that this isn't really possible. We can however get a very rough (mostly worthless) idea by enabling the -S flag which will subtract dependents downloads from <package> downloads. Note that this is just an estimate as are all download counts.
