+# The "New" in this TestNew means that this is the place to develop a new test for the mains dir.
+# If you just pop a file in the source directory, all tests will run. (Well, actually guard does
+#  not pick up changes on that source dir yet, but when you run it manually, all tests run)
+# This is fine if all is fine. But if all is fine, you are not developing, just playing.
+# So when you really need to itereate this editing this gives guard auto-run and just of that
+# one test that you work on.
+
+# After getting the test to run, copy paste the whole code into a file in source and revert
+# changes on this file.
