[gentoo-user] USE flags handling

[behrouz khosravi]

Hello everyone.
I just concurred my fear and jumped to installing gentoo!
So far so good!
Before installing on my laptop and desktop, I am trying on virtual box
and the system is running Fluxbox very good.(default profile)
Now I am thinking about managing USE flags.
What if I  disable everything in the make.conf ( I mean USE="-*" ) and
gradually add the needed flags to package.use?
I am not trying to have severe control, I just want to expand my knowledge!
thanks.
