Review Comment:
Thanks for that! I was looking through it and just have two questions:
1. Is that maybe overkill given that we aren't looking to provide full
manifest interactions, just a simple parse to get the shared lib path?
2. How do I modify that to express that the `shared` member could be
*either* a string or a `map<string, string>` that maps platform triples to a
path?
