50 longDescription = ''
51 Astring exposes an alternative String module for OCaml. This module tries
52 to balance minimality and expressiveness for basic, index-free, string
53 processing and provides types and functions for substrings, string sets
54 and string maps.
55
56 Remaining compatible with the OCaml String module is a non-goal.
57 The String module exposed by Astring has exception safe functions, removes
58 deprecated and rarely used functions, alters some signatures and names,
59 adds a few missing functions and fully exploits OCaml's newfound string
60 immutability.
