Since astring is a common dependency and the maintainance effort is minimal (package dependencies and build system didn't change) we keep the old 0.8.3 version around for OCaml < 4.05, since 0.8.4 requires a minimum of OCaml 4.05.

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.
