proj/gentoo: Initial commit

This commit represents a new era for Gentoo:
Storing the gentoo-x86 tree in Git, as converted from CVS.

This commit is the start of the NEW history.
Any historical data is intended to be grafted onto this point.

Creation process:
1. Take final CVS checkout snapshot
2. Remove ALL ChangeLog* files
3. Transform all Manifests to thin
4. Remove empty Manifests
5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$
5.1. Do not touch files with -kb/-ko keyword flags.

+# @BLURB: convenience functions to handle localizations
+# @DESCRIPTION:
+# The l10n (localization) eclass offers a number of functions to more
+# conveniently handle localizations (translations) offered by packages.
+# These are meant to prevent code duplication for such boring tasks as
+# determining the cross-section between the user's set LINGUAS and what
+# is offered by the package; and generating the right list of linguas_*
+# USE flags.
+
+# @ECLASS-VARIABLE: PLOCALES
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# Variable listing the locales for which localizations are offered by
+# the package. Check profiles/desc/linguas.desc to see if the locales
+# are listed there. Add any missing ones there.
+#
+# Example: PLOCALES="cy de el_GR en_US pt_BR vi zh_CN"
+
+# @ECLASS-VARIABLE: PLOCALE_BACKUP
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# In some cases the package fails when none of the offered PLOCALES are
+# selected by the user. In that case this variable should be set to a
+# default locale (usually 'en' or 'en_US') as backup.
+#
+# Example: PLOCALE_BACKUP="en_US"
+
+# Add linguas useflags
+for u in ${PLOCALES}; do
+	IUSE+=" linguas_${u}"
+done
+
+# @FUNCTION: l10n_for_each_locale_do
+# @USAGE: <function>
+# @DESCRIPTION:
+# Convenience function for processing localizations. The parameter should
+# be a function (defined in the consuming eclass or ebuild) which takes
+# an individual localization as (last) parameter.
+#
+# Example: l10n_for_each_locale_do install_locale
+l10n_for_each_locale_do() {
+	local locs x
+	locs=$(l10n_get_locales)
+	for x in ${locs}; do
+		"${@}" ${x} || die "failed to process enabled ${x} locale"
+	done
+}
+
+# @FUNCTION: l10n_for_each_disabled_locale_do
+# @USAGE: <function>
+# @DESCRIPTION:
+# Complementary to l10n_for_each_locale_do, this function will process
+# locales that are disabled. This could be used for example to remove
+# locales from a Makefile, to prevent them from being built needlessly.
+l10n_for_each_disabled_locale_do() {
+	local locs x
+	locs=$(l10n_get_locales disabled)
+	for x in ${locs}; do
+		"${@}" ${x} || die "failed to process disabled ${x} locale"
+	done
+}
+
+# @FUNCTION: l10n_find_plocales_changes
+# @USAGE: <translations dir> <filename pre pattern> <filename post pattern>
+# @DESCRIPTION:
+# Ebuild maintenance helper function to find changes in package offered
+# locales when doing a version bump. This could be added for example to
+# src_prepare
+#
+# Example: l10n_find_plocales_changes "${S}/src/translations" "${PN}_" '.ts'
+l10n_find_plocales_changes() {
+	[[ $# -ne 3 ]] && die "Exactly 3 arguments are needed!"
+	einfo "Looking in ${1} for new locales ..."
+	pushd "${1}" >/dev/null || die "Cannot access ${1}"
+	local current= x=
+	for x in ${2}*${3} ; do
+		x=${x#"${2}"}
+		x=${x%"${3}"}
+		current+="${x} "
+	done

+		einfo "There are changes in locales! This ebuild should be updated to:"
+		einfo "PLOCALES=\"${current%[[:space:]]}\""
+	else
+		einfo "Done"
+	fi
+}
+
+# @FUNCTION: l10n_get_locales
+# @USAGE: [disabled]
+# @DESCRIPTION:
+# Determine which LINGUAS USE flags the user has enabled that are offered
+# by the package, as listed in PLOCALES, and return them. In case no locales
+# are selected, fall back on PLOCALE_BACKUP. When the disabled argument is
+# given, return the disabled useflags instead of the enabled ones.
