<para>To test the results, issue:
<userinput>make check</userinput>. This takes a long time, about 2 SBUs.</para>

<term><command>autoconf</command></term>
<listitem>
<indexterm zone="ch-system-autoconf autoconf"><primary sortas="b-autoconf">autoconf</primary></indexterm>
<para>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 it produces are
independent -- running them does not require the autoconf program.</para>
</listitem>
</varlistentry>

<term><command>autoheader</command> </term>
<listitem>
<indexterm zone="ch-system-autoconf autoheader"><primary sortas="b-autoheader">autoheader</primary></indexterm>
<para>is a tool for creating template files 
of C #define statements for configure to use.</para>

<varlistentry xml:id="autom4te">
<term><command>autom4te</command></term>
<listitem>
<indexterm zone="ch-system-autoconf autom4te"><primary sortas="b-autom4te">autom4te</primary></indexterm>
<para>is a wrapper for the M4 macro processor.</para>
</listitem>

<varlistentry xml:id="autoreconf">
<term><command>autoreconf</command></term>
<listitem>
<indexterm zone="ch-system-autoconf autoreconf"><primary sortas="b-autoreconf">autoreconf</primary></indexterm>
<para>comes in handy when there are a lot
of autoconf-generated configure scripts around. The program runs autoconf and
autoheader repeatedly (where appropriate) to remake the autoconf configure
scripts and configuration header templates in a given directory tree.</para>
</listitem>
</varlistentry>

<varlistentry xml:id="autoscan">
<term><command>autoscan</command> </term>
<listitem>
<indexterm zone="ch-system-autoconf autoscan"><primary sortas="b-autoscan">autoscan</primary></indexterm>
<para>can help to create a
<filename>configure.in</filename> file for a software package. It examines
the source files in a directory tree, searching them for common portability
problems and creates a <filename>configure.scan</filename> file that serves as
as a preliminary <filename>configure.in</filename> for the package.</para>
</listitem>
</varlistentry>

<varlistentry xml:id="autoupdate">
<term><command>autoupdate</command></term>
<listitem>
<indexterm zone="ch-system-autoconf autoupdate"><primary sortas="b-autoupdate">autoupdate</primary></indexterm>
<para>modifies a <filename>configure.in</filename> file that still calls autoconf 
macros by their old names to use the current macro names.</para>
</listitem>
</varlistentry>

<varlistentry xml:id="ifnames">
<term><command>ifnames</command> </term>
<listitem>
<indexterm zone="ch-system-autoconf ifnames"><primary sortas="b-ifnames">ifnames</primary></indexterm>
<para>can be helpful when writing a
<filename>configure.in</filename> for a software package. It prints the
identifiers that the package uses in C preprocessor conditionals. If a package
has already been set up to have some portability, this program can help to
determine what <command>configure</command> needs to check. It can fill
in some gaps in a <filename>configure.in</filename> file generated by
autoscan.</para>
