For some reason they all have their executable bits set. Presumably this
is because they were made on an NTFS system where every file is
executable (which doesn't sound secure at all but that's another story).
This allows translators to test all text boxes in the scripts. It
doesn't run the scripts themselves - it only shows the basic appearance
of each text box individually, so context may be lost but it's good to
have a way to see any text boxes that might otherwise not be easily
seen because they require specific circumstances to appear.
