title: What is the difference between build.sbt and build.scala?
body: <p>I started to learn Scala and almost in every tutorial I see a <code>build.sbt</code> file which describes project settings. But now I have installed <code>giter8</code> and created a project from template. And generated project from template missed <code>build.sbt</code> file, but it have <code>build.scala</code> (which seems used for same purposes, but it is more flexible).   </p>
  
  <p>So what is the difference between <code>build.sbt</code> and <code>build.scala</code>?<br>
  Which is more preferred and why?</p>
