[TYPO3-english] getting $GLOBALS['TSFE']->tmpl->setup[plugin.][myext] in eID

[Domi]

Hello,

I try to get all my configuration values from ext_typoscript_setup.txt 
inside of my eID PHP script. But I dont find which instances I need to 
load for this.

I tried
$GLOBALS['TSFE'] = t3lib_div::makeInstance('tslib_fe',  $TYPO3_CONF_VARS);
But this was not right. Does anyone knows, what I need to load if I want 
to save the configuration of my plugin like this:
$conf = GLOBALS['TSFE']->tmpl->setup['plugin.']['myext.'];

Thanks,
Dominic
