+
+This is a translatable XML Entity file.
+See doc-base/script/text-entities.php for details.
+
+Place here small entities that are expected to be translated.
+For big or complex entities, please create an individual entity
+file at doc-lang/entities/entityname.xml.
+
+Keep the lines strictly under 79 columns, to make the process of
+manual translation easier, and to not wrap around on automatic
+emails.
