+Expected result
+===============
+This test application is polling all available SAUL devices periodically for
+their data. This data is then printed to STDIO.
+
+Background
+==========
+The actual devices that are actually polled depend on the devices that are
+configured for a particular platform. If you want to test the SAUL interface
+to a particular device, you should just connect it to your BOARD and include
+the corresponding device driver using the `USEMODULE` environment variable.
