The new Use-Auto transform replaces the type specifier for variable declarations with the special C++11 'auto' type specifier. For now, the replacement is done only for variables that are iterators of any of the std containers and only if the type used is one of those explicitly allowed by the standard (i.e. not an implementation-specific type).
