Distributing Autoconf Output **************************** [excerpt from autoconf documentation] The configuration scripts that Autoconf produces are covered by the GNU General Public License. This is because they consist almost entirely of parts of Autoconf itself, rearranged somewhat, and Autoconf is distributed under the terms of the GPL. As applied to Autoconf, the GPL just means that you need to distribute `configure.in' along with `configure'. Programs that use Autoconf scripts to configure themselves do not automatically come under the GPL. Distributing an Autoconf configuration script as part of a program is considered to be *mere aggregation* of that work with the Autoconf script. Such programs are not derivative works based on Autoconf; only their configuration scripts are. We still encourage software authors to distribute their work under terms like those of the GPL, but doing so is not required to use Autoconf.
