 Karax is a framework for developing single page applications in Nim.
 It's still in heavy development, so keep in mind that the API is subject

 - Leverage Nim's macro system to produce a framework that allows
   for the development of applications that are boilerplate free.
 - Keep it small, keep it fast, keep it flexible.
