"""
This script will collect the contributors to friendica and its translations from
  * the git log of the friendica core and addons repositories
  * the translated messages.po from core and the addons.
The collected names will be saved in CREDITS.txt which is also parsed from
yourfriendica.tld/credits.

The output is not perfect, so remember to open a fresh (re)created credits.txt file
in your fav editor to check for obvious mistakes and doubled entries.

Initially written by Tobias Diekershoff for the Friendica Project. Released under
the terms of the AGPL version 3 or later, same as Friendica.
