6# @MAINTAINER:
7# base-system@gentoo.org
8# @BLURB: many extra (but common) functions that are used in ebuilds
9# @DESCRIPTION:
10# The eutils eclass contains a suite of functions that complement
11# the ones that ebuild.sh already contain. The idea is that the functions
12# are not required in all ebuilds but enough utilize them to have a common
13# home rather than having multiple ebuilds implementing the same thing.
4# 14#
5# This eclass is for general purpose functions that most ebuilds 15# Due to the nature of this eclass, some functions may have maintainers
6# have to implement themselves. 16# different from the overall eclass!

1692# A temporary hack until portage properly supports DEPENDing on USE
1693# flags being enabled in packages. This will check to see if the specified
1694# DEPEND atom was built with the specified list of USE flags. The
1695# --missing option controls the behavior if called on a package that does
1696# not actually support the defined USE flags (aka listed in IUSE).
1697# The default is to abort (call die). The -a and -o flags control
1698# the requirements of the USE flags. They correspond to "and" and "or"
1699# logic. So the -a flag means all listed USE flags must be enabled
1700# while the -o flag means at least one of the listed IUSE flags must be
1701# enabled. The --hidden option is really for internal use only as it
1702# means the USE flag we're checking is hidden expanded, so it won't be found
1703# in IUSE like normal USE flags.
