You don't need this unless you're planning on writing a script that runs alongside Replay Rewrite.
Ce script ne devrait pas être installé directement. C'est une librairie créée pour d'autres scripts. Elle doit être inclus avec la commande // @require https://update.greasyfork.org/scripts/418636/880565/libpbr21.js
this is the original library by pabst, used by many of his scripts.
I'm merely trying to make it usable today by loading it in https versions of pages and making minor changes.
