+
+<para>
+Autoconf is a tool for producing shell scripts that automatically
+configure software source code packages to adapt to many kinds of
+UNIX-like systems.  The configuration scripts produced by Autoconf are
+independent of Autoconf when they are run, so their users do not need to
+have Autoconf.

+
+<sect3><title>autoheader</title>
+
+<para>
+The autoheader program can create a template file of C #define
+statements for configure to use

+<sect3><title>autoreconf</title>
+
+<para>
+If you have a lot of Autoconf-generated configure scripts, the
+autoreconf program can save you some work.  It runs autoconf (and
+autoheader, where appropriate) repeatedly to remake the Autoconf
+configure scripts and configuration header templates in the directory
+tree rooted at the current directory.
+</para>
+
+</sect3>
+
+<sect3><title>autoscan</title>
+
+<para>
+The autoscan program can help you create a configure.in file for
+a software package. autoscan examines source files in the directory
+tree rooted at a directory given as a command line argument, or the
+current directory if none is given.  It searches the source files for
+common portability problems and creates a file configure.scan which
+is a preliminary configure.in for that package.
+</para>
+
+</sect3>
+
+<sect3><title>autoupdate</title>
+
+<para>
+The autoupdate program updates a configure.in file that calls
+Autoconf macros by their old names to use the current macro names.
+</para>
+
+</sect3>
+
+<sect3><title>ifnames</title>
+
+<para>
+ifnames can help when writing a configure.in for a software
+package. It prints the identifiers that the package already uses in C
+preprocessor conditionals. If a package has already been set up to
+have some portability, this program can help you figure out what its
+configure needs to check for. It may help fill in some gaps in a
+configure.in generated by autoscan.
