+The files here contain additional translations for various files
+distributed with Remind.
+
+If you create a file in $SysInclude whose name is "myfile.rem", then
+you can enable translation by putting this at the top of your
+file:
+
+#===================================================================
+# Localize if we can
+IF access($SysInclude + "/translations/" + _("LANGID") + "/myfile.rem", "r") >= 0
+    SYSINCLUDE translations/[_("LANGID")]/myfile.rem
+ENDIF
+#===================================================================
+
+Then you can localize your file by putting appropriate TRANSLATION directives
+in the file $SysInclude/translations/<LC>/myfile.rem where <LC> is the
+two-character language code.
