 // A handy class that takes care of setting up and destroying a
-// csync::UserShare instance for unit tests that require one.
+// syncer::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) {
-//     csync::ReadTransaction trans(test_user_share_.user_share());
+//     syncer::ReadTransaction trans(test_user_share_.user_share());
 //     ...
 //   }
 //
