 Date strings to translate per each language for display and parsing.

+    LANG=fr_FR.utf8 LC_ALL=fr_FR.utf8 GRAMPS_RESOURCES=$PWD python -m gramps.gen.datehandler._datestrings

+Then merge the output into your language's .po file, and further modify the
+strings as needed. Then remove the strings from your language's
+:class:`DateParserXX` and :class:`DateHandlerXX` classes.
