-# @BLURB: common ebuild functions for autotools-based packages
-# @DESCRIPTION:
-# autotools-utils.eclass is autotools.eclass(5) and base.eclass(5) wrapper
-# providing all inherited features along with econf arguments as Bash array,
-# out of source build with overridable build dir location, static archives
-# handling, libtool files removal.
-#
-# Please note that autotools-utils does not support mixing of its phase
-# functions with regular econf/emake calls. If necessary, please call
-# autotools-utils_src_compile instead of the latter.

-# @EXAMPLE:
-# Typical ebuild using autotools-utils.eclass:
-#

-# If your tool is not supported, please open a bug and we'll add support for it.

-# @BLURB: A common eclass for Lua packages
-# @DESCRIPTION:
-# A common eclass providing helper functions to build and install
-# packages supporting being installed for multiple Lua implementations.
-#
-# This eclass sets correct IUSE. Modification of REQUIRED_USE has to
-# be done by the author of the ebuild (but LUA_REQUIRED_USE is
-# provided for convenience, see below). The eclass exports LUA_DEPS
-# and LUA_USEDEP so you can create correct dependencies for your
-# package easily. It also provides methods to easily run a command for
-# each enabled Lua implementation and duplicate the sources for them.
-#
-# Note that since this eclass always inherits lua-utils as well, in ebuilds
-# using the former there is no need to explicitly inherit the latter in order
-# to use helper functions such as lua_get_CFLAGS.
-#
-# @EXAMPLE:
-# @CODE
-# EAPI=7
-#
-# LUA_COMPAT=( lua5-{1..3} )
-#
-# inherit lua
-#
-# [...]
-#
-# REQUIRED_USE="${LUA_REQUIRED_USE}"
-# DEPEND="${LUA_DEPS}"
-# RDEPEND="${DEPEND}
-#     dev-lua/foo[${LUA_USEDEP}]"
-# BDEPEND="virtual/pkgconfig"
-#
-# lua_src_install() {
-#     emake LUA_VERSION="$(lua_get_version)" install

-# @ECLASS-VARIABLE: LUA_COMPAT
-# @REQUIRED
-# @PRE_INHERIT
-# @DESCRIPTION:
-# This variable contains a list of Lua implementations the package
-# supports. It must be set before the `inherit' call. It has to be
-# an array.
-#
-# Example:
-# @CODE
-# LUA_COMPAT=( lua5-1 lua5-2 lua5-3 )
-# @CODE
-#
-# Please note that you can also use bash brace expansion if you like:
-# @CODE
-# LUA_COMPAT=( lua5-{1..3} )
-# @CODE
-
-# @ECLASS-VARIABLE: LUA_COMPAT_OVERRIDE
-# @USER_VARIABLE
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# This variable can be used when working with ebuilds to override
-# the in-ebuild LUA_COMPAT. It is a string listing all
-# the implementations which package will be built for. It need be
-# specified in the calling environment, and not in ebuilds.
-#
-# It should be noted that in order to preserve metadata immutability,
-# LUA_COMPAT_OVERRIDE does not affect IUSE nor dependencies.
-# The state of LUA_TARGETS is ignored, and all the implementations
-# in LUA_COMPAT_OVERRIDE are built. Dependencies need to be satisfied
-# manually.
-#
-# Example:
-# @CODE
-# LUA_COMPAT_OVERRIDE='lua5-2' emerge -1v dev-lua/foo
-# @CODE
-
-# @ECLASS-VARIABLE: LUA_REQ_USE
-# @DEFAULT_UNSET
-# @PRE_INHERIT
-# @DESCRIPTION:
-# The list of USE flags required to be enabled on the chosen Lua
-# implementations, formed as a USE-dependency string. It should be valid
-# for all implementations in LUA_COMPAT, so it may be necessary to
-# use USE defaults.
-# This must be set before calling `inherit'.
-#
-# Example:
-# @CODE
-# LUA_REQ_USE="deprecated"
-# @CODE
-#
-# It will cause the Lua dependencies to look like:
-# @CODE
-# lua_targets_luaX-Y? ( dev-lang/lua:X.Y[deprecated] )
-# @CODE
-
-# @ECLASS-VARIABLE: BUILD_DIR
-# @OUTPUT_VARIABLE
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# The current build directory. In global scope, it is supposed to
-# contain an initial build directory; if unset, it defaults to ${S}.
-#
-# In functions run by lua_foreach_impl(), the BUILD_DIR is locally
-# set to an implementation-specific build directory. That path is
-# created through appending a hyphen and the implementation name
-# to the final component of the initial BUILD_DIR.
-#
-# Example value:
-# @CODE
-# ${WORKDIR}/foo-1.3-lua5-1
-# @CODE
-
-# @ECLASS-VARIABLE: LUA_DEPS
-# @OUTPUT_VARIABLE
-# @DESCRIPTION:
-# This is an eclass-generated Lua dependency string for all
-# implementations listed in LUA_COMPAT.
-#
-# Example use:
-# @CODE
-# RDEPEND="${LUA_DEPS}
-#   dev-foo/mydep"
-# DEPEND="${RDEPEND}"
-# @CODE
-#
-# Example value:
-# @CODE
-# lua_targets_lua5-1? ( dev-lang/lua:5.1 )
-# lua_targets_lua5-2? ( dev-lang/lua:5.2 )
-# @CODE
-
-# @ECLASS-VARIABLE: LUA_REQUIRED_USE
-# @OUTPUT_VARIABLE
-# @DESCRIPTION:
-# This is an eclass-generated required-use expression which ensures at
-# least one Lua implementation has been enabled.
-#
-# This expression should be utilized in an ebuild by including it in
-# REQUIRED_USE, optionally behind a use flag.
-#
-# Example use:
-# @CODE
-# REQUIRED_USE="lua? ( ${LUA_REQUIRED_USE} )"
-# @CODE
-#
-# Example value:
-# @CODE
-# || ( lua_targets_lua5-1 lua_targets_lua5-2 )
-# @CODE
-
-# @ECLASS-VARIABLE: LUA_USEDEP
-# @OUTPUT_VARIABLE
-# @DESCRIPTION:
-# This is an eclass-generated USE-dependency string which can be used to
-# depend on another Lua package being built for the same Lua
-# implementations.
-#
-# Example use:
-# @CODE
-# RDEPEND="dev-lua/foo[${LUA_USEDEP}]"
