+// This file implements a universal value printer that can print a
+// value of any type T:
+//
+// void ::testing::internal::UniversalPrinter<T>::Print(value, ostream_ptr);
+//
+// A user can teach this function how to print a class type T by
+// defining either operator<<() or PrintTo() in the namespace that
+// defines T. More specifically, the FIRST defined function in the
+// following list will be used (assuming T is defined in namespace
+// foo):
+//
+// 1. foo::PrintTo(const T&, ostream*)
+// 2. operator<<(ostream&, const T&) defined in either foo or the
+// global namespace.
+//
+// If none of the above is defined, it will print the debug string of
+// the value if it is a protocol buffer, or print the raw bytes in the
+// value otherwise.
+//
+// To aid debugging: when T is a reference type, the address of the
+// value is also printed; when T is a (const) char pointer, both the
+// pointer value and the NUL-terminated string it points to are
+// printed.
+//
+// We also provide some convenient wrappers:
+//
+// // Prints a value to a string. For a (const or not) char
+// // pointer, the NUL-terminated string (but not the pointer) is
+// // printed.
+// std::string ::testing::PrintToString(const T& value);
+//
+// // Prints a value tersely: for a reference type, the referenced
+// // value (but not the address) is printed; for a (const or not) char
+// // pointer, the NUL-terminated string (but not the pointer) is
+// // printed.
+// void ::testing::internal::UniversalTersePrint(const T& value, ostream*);
