title: scala c integration
body: <p>I would like to port some of my scala code to c and call this ported code from my current project. But I did not find any documentation about how to do that. It would be great if this would be possible just from sbt, because thats my current build system.</p>
  
  <p>Currently I have heared about SNA, but without documentation</p>
  
  <p>I am not looking for an automatic scala to c compiler or anything like that. I just don't know how to write the interface between scala and c</p>
