Let’s say you have a Deps.toml file:

- [Deps.toml](https://github.com/JuliaRegistries/General/blob/master/L/LightGraphs/Deps.toml)

How do you parse it to get the dependency packages that the latest version would have?

One hiccup is I have no clue what `["0.14-0"]` means as I assume `v0` comes before `v0.14`:

```julia
["0.14-0"]
Arpack = "7d9fca2a-8960-54d3-9f78-7d1dccf2cb97"

```

I _think_ it means, “starting at v0.14 and continuing through any version that is in major version 0”.
