+"""
+This script is used to simplify the translation process.
+
+Django provides a framework for working out which strings are "translatable",
+and these strings are then dumped in a file under InvenTree/locale/<lang>/LC_MESSAGES/django.po
+
+This script presents the translator with a list of strings which have not yet been translated,
+allowing for a simpler and quicker translation process.
+
+If a string translation needs to be updated, this will still need to be done manually,
+by editing the appropriate .po file.
