|

| [cf24ff1] | 10 | <para>autoconf is a tool for producing shell scripts that automatically
|
|---|
| [6370fa6] | 11 | configure software source code packages to adapt to many kinds of
|
|---|
| [32cee45c] | 12 | Unix-like systems. The configuration scripts produced by autoconf are
|
|---|
| [cf24ff1] | 13 | independent of autoconf when they are run, so their users do not need to
|
|---|
| 14 | have autoconf.</para></sect4>

|

| [b822811] | 17 | <para>The autoheader program can create a template file of C #define

|

| [cf24ff1] | 21 | <para>If there are a lot of autoconf-generated configure scripts, the
|
|---|
| [3cc70a0] | 22 | autoreconf program can save some work. It runs autoconf (and
|
|---|
| [cf24ff1] | 23 | autoheader, where appropriate) repeatedly to remake the autoconf
|
|---|
| [6370fa6] | 24 | configure scripts and configuration header templates in the directory

|
|---|
| [b822811] | 28 | <para>The autoscan program can help to create a configure.in file for
|
|---|
| [6370fa6] | 29 | a software package. autoscan examines source files in the directory
|
|---|
| 30 | tree rooted at a directory given as a command line argument, or the
|
|---|
| 31 | current directory if none is given. It searches the source files for
|
|---|
| 32 | common portability problems and creates a file configure.scan which
|
|---|
| [bdc08c1] | 33 | is a preliminary configure.in for that package.</para></sect4>

|
|---|
| [b822811] | 36 | <para>The autoupdate program updates a configure.in file that calls
|
|---|
| [cf24ff1] | 37 | autoconf macros by their old names to use the current
|
|---|
| [bdc08c1] | 38 | macro names.</para></sect4>

|
|---|
| [b822811] | 41 | <para>ifnames can help when writing a configure.in for a software
|
|---|
| [6370fa6] | 42 | package. It prints the identifiers that the package already uses in C
|
|---|
| 43 | preprocessor conditionals. If a package has already been set up to
|
|---|
| [3cc70a0] | 44 | have some portability, this program can help to figure out what its
|
|---|
| [6370fa6] | 45 | configure needs to check for. It may help fill in some gaps in a
|
|---|
| [bdc08c1] | 46 | configure.in generated by autoscan.</para></sect4>
