+This library contains several MRT Scenarios which define a predefined scenario for simulating MRT files with specific configurations.\

+The syntax for the `scenario.json` files is the following.
+```json
+{
+    "name": "Test Scenario 1",
+    "description": "This is a test scenario.",
+    "no_rabbitmq_direct": false,
