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