#
# USE_LIBLTDL=yes
#   - Convenience knob to depend on the library from devel/libltdl15
#
# USE_LIBTOOL_VER=<value>
#   - Port wishes to use libtool, including the configuration step
#   - Port will use the ports version of libtool
#   - Implies GNU_CONFIGURE?=yes and WANT_LIBTOOL_VER=<value>
#
# USE_INC_LIBTOOL_VER=<value>
#   - Port wishes to use libtool, including the configuration step

#     This is a NULL-OP if neither {USE,WANT}_LIBTOOL_VER are defined
#
# LIBTOOLFLAGS=<value>
#   - Arguments passed to libtool during configure step
#     Currently defaults to "--disable-ltlibs", but this will be going
#     away when libtool .la files are brought back
#
# LIBTOOLFILES=<list-of-files>
#   - A list of files to patch during libtool pre-configuration
#     Defaults to "aclocal.m4" if autoconf is in use, otherwise "configure"
#
#---------------------------------------------------------------------------
# Major changes:
#
# - USE_AUTOMAKE, USE_AUTOCONF, USE_AUTOHEADER, and USE_LIBTOOL have
#   been deprecated in favor of USE_<x>_VER=...
#   As of 4/21/2004, changes should be made as follows:
#       USE_AUTOMAKE        -> USE_AUTOMAKE_VER=14
#       USE_AUTOCONF        -> USE_AUTOCONF_VER=213
#       USE_AUTOHEADER      -> USE_AUTOHEADER_VER=213
#       USE_LIBTOOL         -> USE_LIBTOOL_VER=13
#
# - additional variables WANT_{AUTOMAKE,AUTOCONF,AUTOHEADER,LIBTOOL}_RUN
#   have been added to include a run-time dependency on the appropriate
#   autotools port, as part of work in progress to remove ALL explicit
#   dependencies on autotools in port Makefiles, in favor of using the
#   autotools knobs
#
# - USE_LIBLTDL has been added as a convenience function to provide
#   a lib dependency on devel/libltdl15, so that if the major version
#   number changes in future, only one item has to be updated
#
# - {WANT,USE}_AUTOMAKE_VER no longer automatically brings in
#   autoconf as before, to allow for greater flexibility in version
#   matching, and to simplify bsd.autotools.mk
#   It is now the port Makefile responsibility to specifically bring
#   in the "appropriate" version of autoconf if automake is specified.
#   The mappings are as follows (automake,autoconf pairs):
#       (14,213) (15,253) (18,259)
#
# - Only set GNU_CONFIGURE automatically if USE_<x>_VER is specified,
#   since WANT_<x>_VER implies that we want the environment, but not
#   the configuration steps.
#
# Things to do:
# - Work on killing off as many "old" autotools ports as possible
#
# - Bring back the installation of libtool .la files by default, removing
#   those FreeBSD-specific knobs added to prevent this
#
# - Migrate the myriad of autotools-related knobs into a single
#   USE_AUTOTOOLS=... (to be defined) variable, akin to USE_GNOME=...
