Hi,

I am an automated script letting you know some .po files have just been
updated.  Unless something unusual is happening, we do weekly pushes on
Tuesdays so any strings committed by then will go live.  To give you an idea of
the number of new strings I will calculate untranslated strings below.

`./stats-po.sh .`

Source files: $EMAIL_SOURCE

If you have any questions please reply to the list.

Thanks so much for all your help!
