-*- text -*- Autoconf Autoconf is an extensible package of M4 macros that produce shell scripts to automatically configure software source code packages. These scripts can adapt the packages to many kinds of UNIX-like systems without manual user intervention. Autoconf creates a configuration script for a package from a template file that lists the operating system features that the package can use, in the form of M4 macro calls. Producing configuration scripts using Autoconf requires GNU M4 and Perl. You should install GNU M4 (version 1.4.5 or later is required; 1.4.11 or later is recommended) and Perl (5.005_03 or later) before configuring Autoconf, so that Autoconf's configure script can find them. The configuration scripts produced by Autoconf are self-contained, so their users do not need to have Autoconf (or GNU M4, Perl, etc.). You can get GNU M4 here: ftp://ftp.gnu.org/gnu/m4/ The file INSTALL should be distributed with packages that use Autoconf-generated configure scripts and Makefiles that conform to the GNU coding standards. The package's README can just give an overview of the package, where to report bugs, and a pointer to INSTALL for instructions on compilation and installation. This removes the need to maintain many similar sets of installation instructions. Be sure to read BUGS (especially if this version is not an official release) and INSTALL. Mail suggestions to firstname.lastname@example.org, report bugs to email@example.com, and submit patches to firstname.lastname@example.org. All changes can be tracked at the read-only email@example.com. Always include the Autoconf version number, which you can get by running `autoconf --version'. Archives of firstname.lastname@example.org can be found in <http://lists.gnu.org/archive/html/bug-autoconf/>, and similarly for the other mailing lists. Licensing Autoconf is released under the General Public License (GPL). Additionally, Autoconf includes a licensing exception in some of its source files; see the respective copyright notices for how your project is impacted by including scripts generated by Autoconf. This version of Autoconf uses GPLv2+ plus the above-mentioned exceptions for its installed executables, as described in COPYING. Meanwhile, several source files within the Autoconf project are under GPLv3+, as described in COPYINGv3; these files are used for building and installing Autoconf, but are not present in the installed programs. The entire Autoconf project will move to GPLv3+ when the exception statements have been reformulated in terms of the Additional Permissions as described in section 7 of GPLv3.
