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 use Perl. However, it
20 is not required in order to use the main Autoconf programs. If it is
21 not present, the affected Autoconf utilities will not be installed.
23 The file INSTALL should be distributed with packages that use
24 Autoconf-generated configure scripts and Makefiles that conform to the
25 GNU coding standards. The package's README can just give an overview
26 of the package, where to report bugs, and a pointer to INSTALL for
27 instructions on compilation and installation. This removes the need
28 to maintain many similar sets of installation instructions.
30 Be sure to read BUGS (especially if this Autoconf is not an official
33 Mail suggestions and bug reports for Autoconf to autoconf@gnu.org.
34 Please include the Autoconf version number, which you can get by
35 running `autoconf --version'.
