  - /remotedebugger -> The DLL for the remote debugger facilities (plus the interpreter DLL itself). 
-					  Use this if you want to embed the intepreter in your application with remote debugging enabled.
- - /repl 		   -> The REPL interpreter. It's not really meant for production as much as to quickly test scripts.
- - /tools		   -> Contains the tests suite and bytecode debugger used to debug the interpreter itself.

+Each directory contains, where applyable, subdirectories for different .NET framework targets:
+
+
+- net35 : 
+This is build targeting .NET 3.5 Client Framework. 
+Use this if you are building an app targeting .NET 3.5 or later, Mono 2.x (or later), Xamarin or Unity 3D.
+
+- net40 : 
+This is build targeting .NET 4.0 Client Framework. 
+Use this if you are building an app targeting .NET 4.0 or later, Mono 3.x or Xamarin.

+Use this if you target these platforms. Note that some functionality (involving file system access or the remote debugger) is not available 
+in this build due to limitations of PCLs.
+You also have to use this library if you target WSA/WP8 apps in Unity3D. Refer to this guide: http://docs.unity3d.com/Manual/windowsstore-plugins.html
