-// A MultiProcessTest is a test class which makes it easier to
-// write a test which requires code running out of process.
-//
-// To create a multiprocess test simply follow these steps:
-//
-// 1) Derive your test from MultiProcessTest. Example:
-//
-//    class MyTest : public MultiProcessTest {
-//    };
-//
-//    TEST_F(MyTest, TestCaseName) {
-//      ...
-//    }
-//
-// 2) Create a mainline function for the child processes and include
-//    testing/multiprocess_func_list.h.
-//    See the declaration of the MULTIPROCESS_TEST_MAIN macro
-//    in that file for an example.
-// 3) Call SpawnChild("foo"), where "foo" is the name of
-//    the function you wish to run in the child processes.
-// That's it!
