Re: [gentoo-user] USE flags information resource

[Alan E. Davis]

Thank you for the insight, Alan.  I am just getting to the point of
understanding this.  As a non -developer/programmer I have been at a loss to
understand these basic points about USE flags.  Over time, they begin to
make sense.  Your pointer about the ebuilds is extremely valuable.

Maybe it's just me, in my cluelessness?  Some flags have not been obvious to
me; others have been ambiguous, at least to me.  Maybe digging for all this
is what makes Gentoo such an excellent experience.  On the other hand, a
little more clarity would not hurt, IMHO.  Beggars can't be choicy, but is
it really not possible to provide a slightly clearer explanation of what a
USE flag does?  I'd better shut up.
