+Add a new integration test by creating a new subfolder
+
+Add a file "test.sh" to that runs the test. "test.sh" should exit with a non-zero exit code 
+and display an error message, if something goes wrong.
+
+* An integration test should reflect real-world setups that use handlebars.
+* It should compile a minimal template and compare the output to an expected output.
+* It should use "../.." as dependency for Handlebars so that the currently built library is used.
+
+Currently, integration tests are only running on Linux, especially in travis-ci.
