It turns off all use flags set in profiles as well as use flag defaults |

The safer way, and the way I would recommend, is to use something like |
| 22 |
euse from gentoolkit to figure out which flags are on and turn off the |

ones you do not want in make.conf instead of turning off everything and |
| 24 |
trying to turn back on the ones you do want. |
