+ (description "Timed references for imperative state. This module provides
+an alternative type for references (or mutable cells) supporting undo/redo
+operations. In particular, an abstract notion of time is used to capture the
+state of the references at any given point, so that it can be restored. Note
+that usual reference operations only have a constant time / memory overhead
+(compared to those of the standard library).
+
+Moreover, we provide an alternative implementation based on the references
+of the standard library (Pervasives module). However, it is less efficient
+than the first one.")
