Thx @maipet !
It's deployed to production 👍
I will bring it also to here https://metafacture.github.io/metafacture-documentation/docs/flux/flux-commands.html#decode-string , it's a manual process atm and the old documentation is no more working.

Documentation is now also up-to-date, see #57.
Closing.
