As you may have notice, the NAM installer run Cleanitol when you're installing
I've just updated the LEX version to that version, http://sc4devotion.com/csxlex/lex_edit.php?lotEDIT=97
It is faster and lighter
It is also able to take a cleanitol file as argument in command line ( might be interesting for uploaders who wish to use cleanitol files )
