These are the base files for Arabic language localization; you need
it to correctly display 8bits arabic characters, and for proper
alfabetical sorting and representation of dates and numbers according
to arabic language conventions.
Note that this package doesn't handle right-to-left and left-to-right
switching when displaying nor the isolate-initial-medial-final shapes
of letters; it is to the xterm, application or virtual console driver
to do that.
