If set to TRUE, the default then variables read in from
    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.
  
Example 13.2. Array of config #variables#
      This examples uses
      {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} loop.
      
<table>
  {section name=r loop=$rows}
  <tr bgcolor="{cycle values=#rowColors#}">
    <td> ....etc.... </td>
  </tr>
  {/section}
</table>
