USE variables

[wizy]

I want to make sure that no sound or xwindows dependancies are emerged in when I emerge things. What would be the optimal USE settings to stop them all?

[proxy]

I use this:

USE="-* <other_vars_i_want_here>"

the -* will remove all default ones first, then just add the ones you want

sorry if the example isnt too clear, i hope you see what i mean
