Please have a look at the documentation for more information:

Special thanks to @biboudis and @liufengyun for creating the initial prototype on top of which this library is written, back in Dotty 0.22! Thanks to Parkhar Saxena and the ScQuilL group for participating in the building of the parser as well as @kubukoz for report.info upstream changes to Dotty.
Finally, I want to offer an immense, heartfelt thanks to @nicolasstucki! Thank you so much Nicolas for helping me bring my codebase through nearly a dozen Dotty betas!
