35 longDescription = ''
36 Astring exposes an alternative String module for OCaml. This module tries
37 to balance minimality and expressiveness for basic, index-free, string
38 processing and provides types and functions for substrings, string sets
39 and string maps.
40
41 Remaining compatible with the OCaml String module is a non-goal.
42 The String module exposed by Astring has exception safe functions, removes
43 deprecated and rarely used functions, alters some signatures and names,
44 adds a few missing functions and fully exploits OCaml's newfound string
45 immutability.
