A Swift script that we use at Hyper to generate licenses for used 3rd party libraries, using https://github.com/mono0926/LicensePlist

try writeLocalizedString(forLanguage: .english)
try writeLocalizedString(forLanguage: .norwegian)
try writeLocalizedString(forLanguage: .swedish)

I think we can write it like, right?
