Set one key at a time: void **setFormatConf** (string *format name*, string *rule name*, string *conf key*, mixed *conf value*)
Set all keys at once: void **setFormatConf** (string *format name*, string *rule name*, array *conf key-value pairs*)

Set the configuration for a rule renderer. For example, to tell the "Table" rule in "Xhtml" format what CSS class to use for data cells...

$wiki =& new Text_Wiki();
$wiki->setRenderConf('Xhtml', 'Table', 'css_td', 'my_td_class');

To set all of the "Table" configuration keys for "Xhtml" at the same time...

$wiki =& new Text_Wiki();

$conf = array(
    'css_table' => 'my_table_class',
    'css_tr' => 'my_tr_class',
    'css_td' => 'my_td_class'
);

$wiki->setRenderConf('Xhtml', 'Table', $conf);

Note: Render rule conf keys may be different from format to format.
