[gentoo-user] New portage adds USE description

[Richard Broersma Jr]

Would anyone be so kind as to point out any documentation that explain the new features of Portage
2.1.

I am primary enterested in the USE=" ... " string that I see when I:

emerge --update --pretend world

Thanks for any answers.

Have a look at the first section in [1] and [2]. Note the references to 
release notes and news file in [2]. If this doesn't answer your question feel 
free to clarify your question.

Thanks for the links.  They explained alot.  I now understand what is meant by the USE parameters
and the "minus" use parameters. But I have a few additional questions.

For example: from "emerge -DuvpN world"
net-im/gaim-1.5.0  USE="eds nls perl spell tcltk* -cjk -debug -gnutls -krb4 -minimal% -nas -silc"
0 kB

Is there any significance to the USE color codes:
RED:    eds, nls, perl, spell
GREEN:  tcltk*
BLUE:   -cjk, -debug, -gnutls, -krb4, -nas, -silc
YELLOW: -minimal%

And also, is there any significance to * and %
tcltk*
-minimal%

Thanks for the your input.

The color is redundant: only serves to hilight what information is
already there. 

RED means that the flag is currently set, and will still be set when
you compile. 

BLUE means the same as the minus sign, meaning that the flag is
currently unset and will still be unset when you compile. 

GREEN means the same as the *, it means that the flag will be changed
compare to the current version. For example, in your output, that
means that the previous version of gaim was compiled without tcltk
support, and the new one will be compiled with tcltk support. 

YELLOW is the same as %, it means that the flag did not exist for the
previous version.

Yes. But that's explained rather well in "man emerge" - search for %
there.

Nonetheless, I also asked this RTFM question a short while back :)
