Hi,

There’s a path to llvm@9 though.
Such examples will of course bitrot over time because they depend on the
dependency graph, which keeps changing. But that’s OK IMO: the goal is
just to give an idea of what the tool can do.

‘node1’ and ‘node2’ are undefined though…

I don’t know, but I’m still unconvinced that ‘--path-to’ is any better
than ‘--path’. In the end, the intended audience consists of people who
know we’re talking about a DAG.
Thanks for your feedback!
