The document discusses the Automake and Autoconf build tools. It defines Automake as a tool that produces portable makefiles to be used by the Make program for compiling software. Autoconf is used to automatically generate configure scripts that conform to GNU coding standards. The key inputs for Automake are configure.ac and Makefile.am files. Automake generates makefiles that allow users to compile programs, clean files, create source distributions, and install/uninstall programs.

Configure Script
A configure script can be used to aid cross-platform compiling. A
suitable configure script should interpret a Makefile.in file and then
create a platform-specific Makefile file.

Automake is a programming tool that produces portable makefiles
for use by the make program, used in compiling software.
It is made by the Free Software Foundation as one of the GNU
programs, and is part of the GNU build system.

So to use automake, there are two input files. They are:
1 configure.ac
2 Makefile.ac

Every configure.ac should have lines like the following:

[hello], [http://hello.example.com/])
AC_PREREQ([2.59])
AM_INIT_AUTOMAKE([1.10 no-define])

Explanation of config.ac File
1 AC INIT macro initializes autoconf with information about
your project, including the project name, version number,
bug-reporting address, tarball name and the project homepage.
2 AC PREREQ(VERSION) macro is optional.
3 AM INIT AUTOMAKE macro takes two arguments: the
name of the package, and a version number.
4 AM CONFIG HEADER macro names the header file which
will hold the preprocessor macro definitions at run time.
5 AC PROG CXX checks for a C++ compiler. If your project
uses C, you can check for a C compiler with AC PROG CC.
6 AC OUTPUT macro takes a list of file names which the
configure process should produce

Features of Automake
Automake generates a makefile that allows the user to:
1 Compile the program.
2 The makefiles produced follow the GNU Coding Standards.
3 Clean (i.e. remove the files resulting from the compilation).
4 Create a source distribution archive (commonly called a
tarball).
5 Install the program in standard directories.
6 Uninstall the program from where it was installed.
