# @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 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 in order 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.

9	# @BLURB: common ebuild functions for autotools-based packages
10	# @DESCRIPTION:
11	# autotools-utils.eclass is autotools.eclass(5) and base.eclass(5) wrapper
12	# providing all inherited features along with econf arguments as Bash array,
13	# out of source build with overridable build dir location, static archives
14	# handling, libtool files removal.
15	#
16	# Please note note that autotools-utils does not support mixing of its phase
17	# functions with regular econf/emake calls. If necessary, please call
18	# autotools-utils_src_compile instead of the latter.
19	#
20	# @EXAMPLE:
21	# Typical ebuild using autotools-utils.eclass:
22	#

24	# EAPI="2"
