# @ECLASS: autotools-utils.eclass
# @MAINTAINER:

# @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:
#
# @CODE
# EAPI="2"
#
# inherit autotools-utils

# @ECLASS-VARIABLE: AUTOTOOLS_AUTORECONF
# @DEFAULT_UNSET
# @DESCRIPTION:
# Set to a non-empty value before calling inherit to enable running autoreconf
# in src_prepare() and adding autotools dependencies.
#
# This is usually necessary when using live sources or applying patches
# modifying configure.ac or Makefile.am files. Note that in the latter case
# setting this variable is obligatory even though the eclass will work without
# it (to add the necessary dependencies).
#
# The eclass will try to determine the correct autotools to run including a few
# external tools: gettext, glib-gettext, intltool, gtk-doc, gnome-doc-prepare.
# If your tool is not supported, please open a bug and we'll add support for it.
#
# Note that dependencies are added for autoconf, automake and libtool only.
# If your package needs one of the external tools listed above, you need to add
# appropriate packages to DEPEND yourself.

# @ECLASS-VARIABLE: BUILD_DIR
# @DEFAULT_UNSET
# @DESCRIPTION:
# Build directory, location where all autotools generated files should be
# placed. For out of source builds it defaults to ${WORKDIR}/${P}_build.
#
# This variable has been called AUTOTOOLS_BUILD_DIR formerly.
# It is set under that name for compatibility.

# @DEFAULT_UNSET
# @DESCRIPTION:

# @DESCRIPTION:
# Specify location of autotools' configure script. By default it uses ${S}.
# @ECLASS-VARIABLE: DOCS
# @DEFAULT_UNSET
# @DESCRIPTION:
# Array containing documents passed to dodoc command.
#
# In EAPIs 4+, can list directories as well.
#
# Example:
# @CODE
# DOCS=( NEWS README )

# Array containing documents passed to dohtml command.
#
# Example:
# @CODE
# HTML_DOCS=( doc/html/ )

# @ECLASS-VARIABLE: PATCHES
# @DEFAULT_UNSET
# @DESCRIPTION:
# PATCHES array variable containing all various patches to be applied.
#
# Example:
# @CODE
# PATCHES=( "${FILESDIR}"/${P}-mypatch.patch )
# @CODE
# @ECLASS-VARIABLE: AUTOTOOLS_PRUNE_LIBTOOL_FILES
# @DEFAULT_UNSET
# @DESCRIPTION:
# Sets the mode of pruning libtool files. The values correspond to
# prune_libtool_files parameters, with leading dashes stripped.
#
# Defaults to pruning the libtool files when static libraries are not
# installed or can be linked properly without them. Libtool files
# for modules (plugins) will be kept in case plugin loader needs them.
#
# If set to 'modules', the .la files for modules will be removed
# as well. This is often the preferred option.
#
# If set to 'all', all .la files will be removed unconditionally. This
# option is discouraged and shall be used only if 'modules' does not
# remove the files.
#
# If set to 'none', no .la files will be pruned ever. Use in corner
# cases only.
# Determine using IN or OUT source build
