 Scapegoat is a Scala static code analyzer, what 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).
 
-A static code analyzer is a tool that flag suspicious language usage in code. This can include behavior likely to lead or bugs, non idiomatic usage of a language, or just code that doesn't conform to specified style guidelines.

 **What's the difference between this project and Scalastyle (or others)?**
 
-Scalastyle is a similar linting tool which focuses mostly on enforcing style/code standards. There's no problems running multiple analysis tools on the same codebase. In fact it could be beneficial as the total set of possible warnings is the union of the inspections of all the enabled tools. The worst case is that the same warnings might be generated by multiple tools.

 ## Usage
 Scapegoat is developed as a scala compiler plugin, which can then be used inside your build tool.
