THIS PROJECT IS NO LONGER MAINTAINED, PLEASE PREFER CIRCE
Automatically derive spray-json JsonFormats, powered by shapeless (no macros were written during the creation of this library).
For documentation, read the scaladocs and for examples read the test cases.
Please read the documentation - especially the caveats - and examples before raising a ticket.
// always check maven central for the lastest release
