Just because some flags have counter-flags by accident,
this does not hold for all flags. It is

The debug USE flag in eix is also about convenience for the user:
If eix segfaults, it prints instructions how to produce a backtrace
in such a way which is most likely useful for upstream to locate
the problem.
Currently, these instructions

The way to control compiler flags in Gentoo is CFLAGS.
That is true. However, there's a problem; you can control package
options of individual packages with USE flags, but you can't control
compilation switches of individual packages with

This is correct, but the problem is that an ebuild author or

necessary for

We've had per-package CFLAGS for quite a long time now. Maybe we need
to advertise this a little more? There would certainly be a market for
some util to manage all the per-package options that we have scattered
