+The Gradle build script provides a way to build an Windows executable. You can even do this on a non-Windows machine. For that purpose you need an external application called
+[Launch4j](http://launch4j.sourceforge.net/). Download it and install it on your local machine. The version used to test this feature is 3.8, but it will probably work with
+other versions too. In addition to this, you need to create an environment variable called `LAUNCH4J_HOME` which points to the folder where you have installed the application.

+After that you can build the exe file by running:
