+    longDescription = ''
+      Astring exposes an alternative String module for OCaml. This module tries
+      to balance minimality and expressiveness for basic, index-free, string
+      processing and provides types and functions for substrings, string sets
+      and string maps.
+
+      Remaining compatible with the OCaml String module is a non-goal.
+      The String module exposed by Astring has exception safe functions, removes
+      deprecated and rarely used functions, alters some signatures and names,
+      adds a few missing functions and fully exploits OCaml's newfound string
+      immutability.
