+// Wrapper around script "System" struct, managing access to its variables.
+// ScriptSystem is a readable/writeable struct which had been exposed to
+// script in older versions of API (deprecated).
+// WARNING: it *MUST* keep its size exact to avoid breaking address offsets
+// when running old scripts. In case of emergency you may use its reserved
+// fields, but it's not recommended to do, as this struct is not a part of
+// the modern API anymore.
