-// 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 ...
-//   }
-//
