NAME
       autoreconf - Update generated configuration files

SYNOPSIS
       autoreconf [OPTION]... [DIRECTORY]...

DESCRIPTION
       Run 'autoconf' and, when needed, 'aclocal', 'autoheader', 'automake',
       'autopoint' (formerly 'gettextize'), 'libtoolize', 'intltoolize', and
       'gtkdocize' to regenerate the GNU Build System files in specified
       DIRECTORIES and their subdirectories (defaulting to '.').

       By default, it only remakes those files that are older than their
       sources.	 If you install new versions of the GNU Build System, you can
       make 'autoreconf' remake all of the files by giving it the '--force'
       option.

   Operation modes:
       -h, --help
	      print this help, then exit

       -V, --version
	      print version number, then exit

       -v, --verbose
	      verbosely report processing

       -d, --debug
	      don't remove temporary files

       -f, --force
	      consider all generated and standard files obsolete

       -i, --install
	      copy missing standard auxiliary files

       --no-recursive
	      don't rebuild sub-packages

       -s, --symlink
	      with -i, install symbolic links instead of copies

       -m, --make
	      when applicable, re-run ./configure && make

       -W, --warnings=CATEGORY
	      report the warnings falling in CATEGORY (comma-separated list
	      accepted)

   Warning categories are:
       cross  cross compilation issues

       gnu    GNU coding standards (default in gnu and gnits modes)

       error  treat all enabled warnings as errors
