+// The Flags class provides a type-safe way of storing OR-combinations of enum
+// values. The Flags<T, S> class is a template class, where T is an enum type,
+// and S is the underlying storage type (usually int).
+//
+// The traditional C++ approach for storing OR-combinations of enum values is to
+// use an int or unsigned int variable. The inconvenience with this approach is
+// that there's no type checking at all; any enum value can be OR'd with any
+// other enum value and passed on to a function that takes an int or unsigned
+// int.
