    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.
