Comment:
in xbps-src and xbps, the license field is just free text so it's more a matter of adding it to [xlint](https://github.com/leahneukirchen/xtools/blob/master/xlint#L417-L431).
xlint already supports WITH (it just translates it to `,`). supporting AND and OR could be done the same way or in a more complex way to actually interpret the expression.
