# This is a clone of dev-libs/nss, but with the IUSE="utils" functionality
# moved into a separate package. This is because we want the util binaries as
# part of the dev/test images (for autotests), but do not want them as part of
# the release image. Because we cannot flip USE flags between dev/release
# images, separate packages are used instead.
