+# tests using a "master image" - this is a "known good" image that is
+# installed onto the device as part of initial setup and will be booted into
+# with no interaction; we can then use it to deploy the image to be tested
+# to a second partition before running the tests.
+#
+# For an example master image, see core-image-testmaster
+# (meta/recipes-extended/images/core-image-testmaster.bb)
