how to add use variables to make.conf?

taskara

how do you add a use variable to your make.conf file?

for example if I want to use CUPS or PDA

where would such entries go ?

just add a line:

USE="cups pda"

If you want to disable a variable add a - before the variable.

USE="-kde -gtk"

As a complete newbie to gentoo ... just booted my first system ... how do I find out just what USE variables are available for what packages, is there a list, do I have to poke around a config file ... I'm bemused at the moment as to how to do this.

Thanks very much ... one more question if I may, please

...

For my first attempt at a solo-flying package installation I'm trying to emerge vim, doing a --pretend I see it installing X, gnome etc. IIRC this is because the .ebuild script for VIM has it depending on a series of USE tags ... hence my first question. It now appears that make.defaults sets a large number of USE tags "on" which means I'll have to have a large number of "-tag" is make.conf to undo them. Since this Linux box will be a web/ssh/ftp/whateverelse server I don't want most of the defaults.

Question: is it safe to simply comment-out this line in /etc/make.profile/make.defaults and then simply USE= in make.conf in the usual way.

The answer would seem an obvious "yes" but will this file get overwritten when I next do an emerge rsync or some other automated Portage process?

Sorry, I'm sure this is an FAQ but the FAQ section doesn't indicate the best way to turn off all the defaults.

So do emerge scripts add items to the USE variable when they are run so that the presence of a package will alter future builds?

- and if so is there a way to tell what ports that are currently installed should be rebuilt because of new USE variables?
