The "pkg info -r" command allows one to find the set of all packages
that -directly- depend upon a given package.

Does there exist any tool or any option to permit the user to find out,
for a given package, not only its direct dependents but also any and
all of the dependents of its dependents, ad infinitum, recursively?
