# This Makefile fragment handles packages that use GNU autoconf.
#
# By default, all of the autoconf-related scripts are marked as
# "missing" by running the GNU missing script in place of the utility.
# This hides the autoconf-related scripts from makefiles that aggressively
# call them when some of the inputs are modified in ways the makefiles
# don't expect.
#
# If a package needs to use GNU autoconf, then the package Makefile
# should contain one of the following lines:
#
#	USE_TOOLS+=	autoconf	# use recent GNU autoconf (>=2.50)
#	USE_TOOLS+=	autoconf213	# use GNU autoconf ~2.13
#
# This will allow the package to invoke "autoconf", "autoreconf", etc.
# by their usual, bare names.
#
# If a particular minimum version of autoconf is required, then the
# package Makefile can additionally set AUTOCONF_REQD to the desired
# version, e.g.:
#
#	AUTOCONF_REQD=	2.54	# use at least autoconf>=2.54
#
# To globally prevent any GNU autoconf handling, set the following
# in the package Makefile:
#
#	AUTOMAKE_OVERRIDE=	no
#
# Keywords: autoconf

# If a package requires autoreconf, the package Makefile should contain
# this line:
#
#	USE_TOOLS+=	autoreconf autoconf automake
#
# Keywords: autoreconf

# Only allow one of "autoconf" and "autoconf213" in USE_TOOLS.
