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!

1696# A temporary hack until portage properly supports DEPENDing on USE
1697# flags being enabled in packages. This will check to see if the specified
1698# DEPEND atom was built with the specified list of USE flags. The
1699# --missing option controls the behavior if called on a package that does
1700# not actually support the defined USE flags (aka listed in IUSE).
1701# The default is to abort (call die). The -a and -o flags control
1702# the requirements of the USE flags. They correspond to "and" and "or"
1703# logic. So the -a flag means all listed USE flags must be enabled
1704# while the -o flag means at least one of the listed IUSE flags must be
1705# enabled. The --hidden option is really for internal use only as it
1706# means the USE flag we're checking is hidden expanded, so it won't be found

1834# @FUNCTION: prepalldocs
1835# @USAGE:
1836# @DESCRIPTION:
1837# Compress files in /usr/share/doc which are not already
1838# compressed, excluding /usr/share/doc/${PF}/html.
1839# Uses the ecompressdir to do the compression.
1840# 2009-02-18 by betelgeuse:
1841# Commented because ecompressdir is even more internal to
1842# Portage than prepalldocs (it's not even mentioned in man 5
1843# ebuild). Please submit a better version for review to gentoo-dev
1844# if you want prepalldocs here.
