-    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.
