+// Construct or initialize QuicReferenceCountedPointer from raw pointer. Here
+// raw pointer MUST be a newly created object. Reference count of a newly
+// created object is undefined, but that will be 1 after being added to
+// QuicReferenceCountedPointer.
+// QuicReferenceCountedPointer is used as a local variable.

+// or, equivalently:

+// T* p = new T();
+// r_ptr = T;
+//
+// QuicReferenceCountedPointer is used as a member variable:
+// MyClass::MyClass() : r_ptr(new T()) {}
+//
+// This is WRONG, since *p is not guaranteed to be newly created:
+// MyClass::MyClass(T* p) : r_ptr(p) {}
+//
+// Given an existing QuicReferenceCountedPointer, create a duplicate that has
+// its own reference on the object:
+// QuicReferenceCountedPointer<T> r_ptr_b(r_ptr_a);
+// or, equivalently:
+// QuicReferenceCountedPointer<T> r_ptr_b = r_ptr_a;
+//
+// Given an existing QuicReferenceCountedPointer, create a
