[gentoo-dev] More suggestions for USE

[Rufiao Valhacouto]

I'd be useful if each ebuild could provide some queries to specify which
USE flags a given package can use, and give some explanations about what
are the end results of using each flag. Also, some kind of 'suggested'
USE flags could be implemented, possibly using some dynamic
configuration hints (eg. if the ebuild detects there is gnome installed,
it can suggest the gnome flag).

I've seen some proposals for implementing a more effective way to
maintain the USE flags for each package, and it seems for me this is a
must. Anyway, it would be nice if emerge/ebuild could record the USE
flags used in the build process for each package to help in the track of
how everything was compiled.
