 # Recyclable.Collections
-`Recyclable.Collections` project is an open source framework for operating dynamic lists at performance close to raw arrays, but fairly unlimited in size. It aims at providing minimal memory footprint. It implements `IList<T>`'s interface and is targeted as direct replacements of `List<T>`, `SortableList<T>`, `PriorityQueue<T>` & similar.
