 Scapegoat is a Scala static code analyzer, which is more colloquially known as a code lint tool or linter. Scapegoat works in a similar vein to Java's [FindBugs](http://findbugs.sourceforge.net/) or [checkstyle](http://checkstyle.sourceforge.net/), or Scala's [Scalastyle](https://github.com/scalastyle/scalastyle).
