Full Configuration Example
--------------------------

Full configurations are written in Scala, so this example would be
placed as project/Build.scala, not build.sbt. The build can be split
into multiple files.

External Builds
---------------

-  `Mojolly Backchat Build <http://gist.github.com/1021873>`_
-  `Scalaz
   Build <https://github.com/scalaz/scalaz/blob/master/project/ScalazBuild.scala>`_
-  Source Code Generation
-  Generates Scaladoc and Scala X-Ray HTML Sources, with a unified view
   of source from all sub-projects
-  Builds an archive will the artifacts from all modules
-  "Roll your own" approach to appending the Scala version to the module
   id of dependencies to allow using snapshot releases of Scala.
