#
# This Makefile fragment handles packages that use GNU automake.
#
# By default, all of the automake-related scripts are marked as
# "missing" by running the GNU missing script in place of the utility.
# This hides the automake-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 automake, then the package Makefile
# should contain one of the following lines:
#
#	USE_TOOLS+=	automake	# use recent GNU automake (>=1.9)
#	USE_TOOLS+=	automake14	# use GNU automake ~1.4
#
# This will allow the package to invoke "aclocal" and "automake" by
# their usual, bare names.
#
# If a particular minimum version of automake is required, then the
# package Makefile can additionally set AUTOMAKE_REQD to the desired
# version, e.g.:
#
#	AUTOMAKE_REQD=	1.8	# use at least automake>=1.8
#
# If a package additionally needs to regenerate configure scripts and
# Makefiles that use gettext, then the package Makefile should contain
# the following line:
#
#	USE_TOOLS+=	gettext-m4	# need gettext.m4 to re-gen files
#
# To globally prevent any GNU automake handling, set the following
# in the package Makefile:
#
#	AUTOMAKE_OVERRIDE=    no
#

# This variable is obsoleted, but continue to allow it until packages
# have been taught to use the new syntax.
