<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>

|
<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>

|
<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>

macros by their old names to use the current macro names.</para>

|
|
<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>
