automatic configure script builder (obsolete version) Obsolete compatibility package of Autoconf 2.13. For use only with packages that cannot easily be updated to use Autoconf 2.50+. This package provides compatibility wrappers for autoconf, autoheader, and autoreconf that attempt to automatically choose which version of Autoconf to use, based on some simple heuristics. For information on these heuristics or how to force use of a particular Autoconf version, see /usr/share/doc/autoconf2.13/README.Debian.gz.
