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!
7#
8# NB: If you add anything, please comment it!

75# @DESCRIPTION:
76# Often times code will want to enable a shell option to change code behavior.
77# Since changing shell options can easily break other pieces of code (which
78# assume the default state), eshopts_push is used to (1) push the current shell
79# options onto a stack and (2) pass the specified arguments to set.
48# 80#
49# To use, simply call: 81# A common example is to disable shell globbing so that special meaning/care
50# 82# may be used with variables/arguments to custom functions. That would be:
51# gen_usr_ldscript libfoo.so 83# @CODE
52# 84# eshopts_push -o noglob
53# Note that you should in general use the unversioned name of 85# for x in ${foo} ; do
54# the library, as ldconfig should usually update it correctly 86# if ...some check... ; then
55# to point to the latest version of the library present. 87# eshopts_pop

1758# @DESCRIPTION:
1759# A temporary hack until portage properly supports DEPENDing on USE
1760# flags being enabled in packages. This will check to see if the specified
1761# DEPEND atom was built with the specified list of USE flags. The
1762# --missing option controls the behavior if called on a package that does
1763# not actually support the defined USE flags (aka listed in IUSE).
1764# The default is to abort (call die). The -a and -o flags control
1765# the requirements of the USE flags. They correspond to "and" and "or"
1766# logic. So the -a flag means all listed USE flags must be enabled
1767# while the -o flag means at least one of the listed IUSE flags must be
1768# enabled. The --hidden option is really for internal use only as it
1769# means the USE flag we're checking is hidden expanded, so it won't be found
1770# in IUSE like normal USE flags.
