+
+// scoped_ptr mimics a built-in pointer except that it guarantees deletion
+// of the object pointed to, either on destruction of the scoped_ptr or via
+// an explicit reset(). scoped_ptr is a simple solution for simple needs;
+// use shared_ptr or std::auto_ptr if your needs are more complex.
+
+// *** NOTE ***
+// If your scoped_ptr is a class member of class FOO pointing to a
+// forward declared type BAR (as shown below), then you MUST use a non-inlined
+// version of the destructor. The destructor of a scoped_ptr (called from
+// FOO's destructor) must have a complete definition of BAR in order to
+// destroy it. Example:
+//
+// -- foo.h --
+// class BAR;
+//
+// class FOO {
+// public:
+// FOO();
+// ~FOO(); // Required for sources that instantiate class FOO to compile!
+//
+// private:
+// scoped_ptr<BAR> bar_;
+// };
+//
+// -- foo.cc --
+// #include "foo.h"
+// FOO::~FOO() {} // Empty, but must be non-inlined to FOO's class definition.
+
+// scoped_ptr_malloc added by Google
+// When one of these goes out of scope, instead of doing a delete or
+// delete[], it calls free(). scoped_ptr_malloc<char> is likely to see
+// much more use than any other specializations.
+
+// release() added by Google
+// Use this to conditionally transfer ownership of a heap-allocated object
+// to the caller, usually on method success.
