17 # -----------------------------------------------
18 # The call with PACKAGE and VERSION arguments is the old style
19 # call (pre autoconf-2.50), which is being phased out. PACKAGE
20 # and VERSION should now be passed to AC_INIT and removed from
21 # the call to AM_INIT_AUTOMAKE.
22 # We support both call styles for the transition. After
23 # the next Automake release, Autoconf can make the AC_INIT
24 # arguments mandatory, and then we can depend on a new Autoconf
25 # release and drop the old call support.
