-// A handy class that takes care of setting up and destroying a
-// UserShare 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() {
-//       test_user_share_.SetUp();
-//     }
-//     virtual void TearDown() {
-//       test_user_share_.TearDown();
-//     }
-//    protected:
-//     TestUserShare test_user_share_;
-//   };
-//
-// Then, in your tests:
-//
-//   TEST_F(AwesomenessTest, IsMaximal) {
-//     ReadTransaction trans(test_user_share_.user_share());
-//     ...
-//   }
-//
