+// static_contained_range_map.h: StaticContainedRangeMap.
+//
+// StaticContainedRangeMap is similar to ContainedRangeMap.  However,
+// StaticContainedRangeMap wraps a StaticMap instead of std::map, and does not
+// support dynamic operations like StoreRange(...).
+// StaticContainedRangeMap provides same RetrieveRange(...) interfaces as
+// ContainedRangeMap.
+//
+// Please see contained_range_map.h for more documentation.
