+// A handy class that takes care of setting up and destroying a
+// syncable::Directory instance for unit tests that require one.
+//
+// The expected usage is to make this a component of your test fixture:
+//
+//   class AwesomenessTest : public testing::Test {
+//    public:
+//     virtual void SetUp() {
+//       metadb_.SetUp();
+//     }
+//     virtual void TearDown() {
+//       metadb_.TearDown();
+//     }
+//    protected:
+//     TestDirectorySetterUpper metadb_;
+//   };
+//
+// Then, in your tests, get at the directory like so:
+//
+//   TEST_F(AwesomenessTest, IsMaximal) {
+//     ScopedDirLookup dir(metadb_.manager(), metadb_.name());
+//     ... now use |dir| to get at syncable::Entry objects ...
+//   }
+//
