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