Is there a way to specify a package master version in a Project.toml file?

The problem for me is that I’m working in a Franklin site and need fixes that I have to apply to GMT.jl but at same time I can’t (automatically) register new versions [because of](https://discourse.julialang.org/t/failing-to-register-new-version-because/82346/7) so the easy solution would be to tell Franklin to install master version, but can’t find a way. Tried `-dev`, `#master`, `@master` but they all error.

You can’t write that in the Project.toml file, but you can write

```julia
using Pkg
Pkg.add(PackageSpec(name="GMT", rev="master"))

```

in a CI Script.

Thanks, I’m trying it now.

EDIT: worked, thanks again.
