-// AlignedMemory is a POD type that gives you a portable way to specify static
-// or local stack data of a given alignment and size. For example, if you need
-// static storage for a class, but you want manual control over when the object
-// is constructed and destructed (you don't want static initialization and
-// destruction), use AlignedMemory:
-//
-// static AlignedMemory<sizeof(MyClass), ALIGNOF(MyClass)> my_class;
-//
-// // ... at runtime:
-// new(my_class.void_data()) MyClass();
-//
-// // ... use it:
-// MyClass* mc = my_class.data_as<MyClass>();
-//
-// // ... later, to destruct my_class:
-// my_class.data_as<MyClass>()->MyClass::~MyClass();
-//
-// Alternatively, a runtime sized aligned allocation can be created:
-//
-// float* my_array = static_cast<float*>(AlignedAlloc(size, alignment));
-//
-// // ... later, to release the memory:
-// AlignedFree(my_array);
-//
-// Or using scoped_ptr:
-//
-// scoped_ptr<float, AlignedFreeDeleter> my_array(
-// static_cast<float*>(AlignedAlloc(size, alignment)));
