%description
    Autoconf is an extensible package of m4 macros that produce shell
    scripts to automatically configure software source code packages.
    These scripts can adapt the packages to many kinds of UNIX-like
    systems without manual user intervention. Autoconf creates a
    configuration script for a package from a template file that lists
    the operating system features that the package can use, in the form
    of m4 macro calls.

    This OpenPKG packages provides the following Autoconf versions:
    - GNU Autoconf %{V_latest} (latest version, the default)
    - GNU Autoconf %{V_older} (older version, as an alternative)
    - GNU Autoconf %{V_ancient} (ancient version, for backward-compatibility)
