5 Autoconf is an extensible package of M4 macros that produce shell
6 scripts to automatically configure software source code packages.
7 These scripts can adapt the packages to many kinds of UNIX-like
8 systems without manual user intervention. Autoconf creates a
9 configuration script for a package from a template file that lists the
10 operating system features that the package can use, in the form of M4
13 Producing configuration scripts using Autoconf requires GNU M4. You
14 must install GNU M4 (version 1.4 or later) before configuring
15 Autoconf, so that Autoconf's configure script can find it. The
16 configuration scripts produced by Autoconf are self-contained, so
17 their users do not need to have Autoconf (or GNU M4).
19 Some optional utilities that come with Autoconf, autoscan and
20 autoupdate, use Perl 5.5. However, it is not required in order to use
21 the main Autoconf programs. If it is not present, the affected
22 Autoconf utilities will not be installed.
24 The file INSTALL should be distributed with packages that use
25 Autoconf-generated configure scripts and Makefiles that conform to the
26 GNU coding standards. The package's README can just give an overview
27 of the package, where to report bugs, and a pointer to INSTALL for
28 instructions on compilation and installation. This removes the need
29 to maintain many similar sets of installation instructions.

34 This version of the package Autoconf uses a fixed version of Automake
35 1.4. If ever you alter some Makefile.am (i.e., if you hack Autoconf
36 itself), you'll have to use either a more recent release of Automake,
37 or download the patch from
