See, because there was a problem with new users that they did not add
USE flags for common stuff, and then was upset later on, we added
'default' use flags ...  You can view them with:

 # grep -A 3  USE /etc/make.profile/make.defaults

To start with a clean slate, do in /etc/make.conf:

----------------------------------------------
USE="-* whatever_USE_flags_you_may_want"
----------------------------------------------

The '-*' means to remove all default USE flags defined in
/etc/make.profile/make.defaults ...

Hope this clears some issues.
