+\$config\_overwrite {#variable.config.overwrite}
+===================
+
+If set to TRUE, the default then variables read in from [config
+files](#config.files) will overwrite each other. Otherwise, the
+variables will be pushed onto an array. This is helpful if you want to
+store arrays of data in config files, just list each element multiple
+times.
+
+This examples uses [`{cycle}`](#language.function.cycle) to output a
+table with alternating red/green/blue row colors with
+`$config_overwrite` = FALSE.
+
+The config file.
+
+
+    # row colors
+    rowColors = #FF0000
+    rowColors = #00FF00
+    rowColors = #0000FF
+
+        
+
+The template with a [`{section}`](#language.function.section) loop.
+
+
+    <table>
+      {section name=r loop=$rows}
+      <tr bgcolor="{cycle values=#rowColors#}">
+        <td> ....etc.... </td>
+      </tr>
+      {/section}
+    </table>
+
+        
+
+See also [`{config_load}`](#language.function.config.load),
+[`getConfigVars()`](#api.get.config.vars),
+[`clearConfig()`](#api.clear.config), [`configLoad()`](#api.config.load)
+and the [config files section](#config.files).
