# Run autoreconf in AUTORECONF_WRKSRC to update configure, Makefile.in and
# other build scripts.
#
# Autoreconf runs the following commands provided by devel/autoconf and
# devel/automake.  Each command applies to a single configure.ac or
# configure.in (old name).  If configure.ac defines subdirectories with their
# own configure.ac (using AC_CONFIG_SUBDIRS), autoreconf will recursively
# update those as well.
#
# aclocal	Looks up definitions of m4 macros used in configure.ac that are
#		not provided by autoconf and copies them from their source *.m4
#		file to aclocal.m4.  Local *.m4 files included with the source
#		code take precedence over systemwide *.m4 files.
# autoconf	Generates configure from configure.ac using macro definitions
#		provided by autoconf itself and aclocal.m4.
# autoheader	Generates a configuration header (typically config.h.in) from
#		configure.ac and the macro definitions in aclocal.m4.  Run by
#		autoreconf if configure.ac (or one of the macros it uses)
#		contains AC_CONFIG_HEADERS, AC_CONFIG_HEADER (undocumented), or
#		AM_CONFIG_HEADER (obsolete).
# automake	Generates Makefile.in from Makefile.am for each Makefile
#		listed in configure.ac (using AC_CONFIG_FILES).  Also updates
#		build scripts like compile, depcomp, install-sh, ylwrap,...
#		Run by autoreconf if configure.ac (or one of the macros it
#		uses) contains AM_INIT_AUTOMAKE.
#
# Autoreconf may also run these additional commands provided by other ports.
# A port needs to have a build depdendency on these ports when that's the case.
#
# autopoint	Provided by devel/gettext-tools.  Updates gettext related *.m4
#		files included with the source code and build scripts such as
#		config.rpath.  Run by autoreconf if configure.ac (or one of the
#		macros it uses) contains AM_GNU_GETTEXT.  A build dependency on
#		devel/gettext-tools can be added with USES+=gettext-tools.
#		Note that autoreconf runs autopoint even if a port has an NLS
#		option and the option is disabled.  The build dependency on
#		gettext-tools is not optional.  If the run dependency on
#		gettext is optional this can be specified with
#		NLS_USES=gettext-runtime.
# libtoolize	Provided by devel/libtool.  Updates libtool related *.m4 files
#		included with the source code and build scripts such as
#		ltmain.sh.  Run by autoreconf if configure.ac  (or one of the
#		macros it uses) contains AC_PROG_LIBTOOL or LT_INIT.  A build
#		dependency on devel/libtool is added implicitly when USES
#		contains both autoreconf and libtool.
