Summary : A GNU tool for automatically configuring source code
URL : http://www.gnu.org/software/autoconf/
License : GPLv3+ and GFDL
Description : GNU Autoconf is a tool for configuring source code and Makefiles.
: Using Autoconf, programmers can create portable and configurable
: packages, since the person building the package is allowed to
: specify various configuration options.
: You should install Autoconf if you are developing software and
: would like to create shell scripts that configure your source code
: packages. If you are installing Autoconf, you will also need to
: install the GNU m4 package.
: Note that the Autoconf package is not required for the end-user
: who may be configuring software with an Autoconf-generated script;
: Autoconf is only required for the generation of the scripts, not
: their use.
