References: #4688. For forward-compatibility; intentionally left undocumented. The `license` stanza is not free-form. There is a limited set of valid symbols, of which the argument must be a member. (The set will later be documented, and probably needs amendments.) Version numbers and variants of licenses are intentionally ommitted. The use-case for `license` is filtering and listing of Casks. We want to avoid becoming a detailed repository of application descriptions: that information can be found at the `homepage` URL.
