Yep, it's a really cool library. I'm pretty new to it myself, but I made a little gist of how one might approach this problem: https://gist.github.com/kevinavery/941e7d67c4f8b104f610

I was kinda surprised by how tricky it was to make a Flow that turned ByteStrings into separate String lines, but it seems like the custom GraphStage approach generalizes really well to more complicated stages.
