  8. *       Totally rewrote and fixed wrap_convert() function with url/img/mail preservation.
  9. * LAST ADDS:    [AS] tag with different highlight FlashMX like
  10. *       you can add one or more personal tags
  11. * LAST CHANGES: IMG now use [IMG="{url}"]{comment}[/IMG] as quote and url.
  12. *       Now [PHP] & [AS] use monospace font on.

  108. *
  109. *   Example with no automatic form generator:
  110. *   $codeLighter->area_buttons = Array('PHP', 'CODE', 'B', 'I', 'U'); // will create only these ordered buttons
  111. *   $codeLighter->createTextareaLighter();
