3 # Make sure we use autoconf 2.60 to generate the "configure" script,
4 # in case we want to commit it. Other than that, version 2.59 is
5 # perfectly fine for our purposes, so people who want to modify
6 # this file just have to remember to set the AC_PREREQ argument
7 # to something that suits their needs.
