How to slim your flex project!!!

Flex is great but a little too big : 1 mega for have all  libraries. For a small project ,that's not very good,So I find a magical option :

With this option, the flex library will be linked with your swf, so :

• ONE swf, not many as usual
• All not used part of library will be erased of your SWF !

On my small project, with embedded font, sprite, mxml, it is from 1300kb to 432kb  ! 3 times less !
Use it without any restriction !
