+        .DESCRIPTION
+            This function will output the Summary.txt log file, this is to be
+            able to debug any problems that potentially occurred during setup.
+            This will pick up the newest Summary.txt log file, so any
+            other log files will be ignored (AppVeyor build worker has
+            SQL Server instances installed by default).
+            This code is meant to work regardless what SQL Server
+            major version is used for the integration test.
