+
+The ListLike module provides a common interface to the various Haskell types
+that are list-like.  Predefined interfaces include standard Haskell lists,
+Arrays, ByteStrings, and lazy ByteStrings.  Custom types can easily be made
+ListLike instances as well.
+
+ListLike also provides for String-like types, such as String and ByteString,
+for types that support input and output, and for types that can handle
+infinite lists.")
