Short reply as I'm on a phone, but thanks! I can add an option to pick the nth field, and to skip the first X lines of the input; I think this'd cover your use

Short reply as I'm on a phone, but thanks! I can add an option to pick the nth field, and to skip the first X lines of the input; I think this'd cover your use case! The code and file format support multiple indices in the same zindex file but I haven't got a decent way to pass command line arguments to define them yet! Watch this space: also feel free to ping me on email for more comments!
