Here is an example of a script that provides (almost) such a tool

```
PACKAGES=irmin
for p in $(opam list --recursive --short --sort --required-by $PACKAGES); do
   echo "$p $(opam show $p -f license)"
done
```

The name of the licenses could probably be standardized a bit to make it
easier to come up with white-lists.
