#
# Run autoreconf in CONFIGURE_WRKSRC to update configure, Makefile.in and
# other build scripts.
#
# Autoreconf encapsulates the following commands.  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.
#		Must be run whenever configure.ac or *.m4 files with macros
#		used in configure.ac have been modified.
#		Must also be run whenever automake must be run because the
#		automake macros in aclocal.m4 must have the same version as the
#		automake command.
# autoconf	Generates configure from configure.ac using macro definitions
#		provided by autoconf itself and aclocal.m4.
#		Must be run whenever configure.ac or aclocal.m4 has been
#		modified.
# autoheader	Generates a configuration header (typically config.h.in) from
#		configure.ac and the macro definitions in aclocal.m4.
#		Must be run whenever configure.ac or aclocal.m4 has been
#		modified and 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
#		specified in configure.ac.  Also updates build scripts like
#		compile, depcomp, install-sh, ylwrap,...
#		Must be run whenever Makefile.am, configure.ac or aclocal.m4
#		has been modified and configure.ac (or one of the macros it
#		uses) contains AM_INIT_AUTOMAKE.
# autopoint	Updates gettext related *.m4 files and build scripts such as
#		config.rpath.
#		If a port uses gettext, this command must be run whenever
#		aclocal must be run such that the gettext macros in aclocal.m4
#		have the same version as the gettext build scripts.
# libtoolize	Updates libtool related *.m4 files and build scripts such as
#		ltmain.sh.
#		If a port uses libtool, this command must be run whenever
#		aclocal must be run such that the libtool macros in aclocal.m4
#		have the same version as the libtool build scripts.
