+; This test is essentially doing very basic things with the opt tool and the
+; new pass manager pipeline. It will be used to flesh out the feature
+; completeness of the opt tool when the new pass manager is engaged. The tests
+; may not be useful once it becomes the default or may get spread out into other
+; files, but for now this is just going to step the new process through its
+; paces.
