[gentoo-dev] USE settings for specific apps

[Tom von Schwerdtner]

Hey all,

    Some people have suggested that they would like to be able to set some
USE variables for specific apps.....examples escape me, but I know it has
been brought up.

    Anyways, I was thinking something along these lines would work:

----
# Global settings
USE = "this that other etc"

# App specific
USE-mozilla = "!this !that foo"
----

Basicaly, the syntax would be "USE-<appname>".  This portion should be
simple enough to impliment, however the variables pose more of a problem
since you dont want to have to repeat all of the normal USE settings for a
specific app and most of the time you just want to specify a USE setting not
to use (hence the !'s).  Special vars might be good here too, like
"defaults" to inherit all the global USE settings...or "no-defaults" to
ignore them all...

.....thats the general idea....comments?
