$config_overwrite
    If set to true (by default), 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 12-3. 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> |
