This is a follow-up from the MediaWiki Dev Summit 2017.
Every day @Raymond runs a process for synchronizing messages in translatewiki and in MediaWiki and its extensions source repos. This consists of running shell scripts, checking diffs, and other steps.
These scripts must be stored in the translatewiki source repo (if they aren't already), and the routine must be documented in a public place so anyone (with an account) will be able to do it.
Thanks!
