+Bidirectional Text
+==================
+This patch adds proper support for Right-To-Left languages, such as Hebrew,
Arabic, and Farsi.
+
+Texts combining both RTL and LTR languages are displayed correctly.
+This is achieved using the GNU FriBiDi library, which is an additional
dependency for this patch.
