 sbt-jrebel-plugin is a plugin for [Simple Build Tool](http://www.scala-sbt.org) that generates configuration files (rebel.xml) for [JRebel](http://www.zeroturnaround.com/jrebel/). A rebel.xml is not always required but is recommended because if you don't have one, JRebel cannot understand the layout of your project and might fail to reload changes. You also cannot reload changes from separate projects.
