DESCRIPTION
       If you have a lot of Autoconf-generated configure scripts,
       the  autoreconf  program  can save you some work.  It runs
       autoconf (and autoheader, where appropriate) repeatedly to
       remake  the  Autoconf  configure scripts and configuration
       header templates in the directory tree rooted at the  cur-
       rent  directory.   By default, it only remakes those files
       that are older than their  configure.ac  or  (if  present)
       aclocal.m4.   Since  autoheader does not change the times-
       tamp of its output file if the file wouldn't be  changing,
       this  is  not  necessarily the minimum amount of work.  If
       you install a  new  version  of  Autoconf,  you  can  make
       autoreconf  remake  all  of  the  files  by  giving it the
       --force option.

       If  you  give   autoreconf   the   --autoconf-dir=dir   or
       --localdir=dir  options,  it  passes them down to autoconf
       and autoheader (with relative paths adjusted properly).

       autoreconf does not support having, in the same  directory
       tree,  both directories that are parts of a larger package
       (sharing aclocal.m4 and acconfig.h), and directories  that
       are  independent  packages (each with their own aclocal.m4
       and acconfig.h).  It assumes that they are all part of the
       same  package,  if you use --localdir, or that each direc-
       tory is a separate package, if you  don't  use  it.   This
       restriction may be removed in the future.

       autoreconf accepts the following options:

       --help

       -h     Print  a  summary  of  the command line options and
              exit.

       --version

       -V     Print the version number of Autoconf and exit.

       --verbose
              Print the name of each directory  where  autoreconf
              runs autoconf (and autoheader, if appropriate).

       --debug

       -d     Don't remove the temporary files.

       --force

       -f     Remake  even  configure  scripts  and configuration
              headers that  are  newer  than  their  input  files
              (configure.ac and, if present, aclocal.m4).

       --install

       -i     Copy missing auxiliary files.  This option is simi-
              lar to the option --add-missing in automake.

       --symlink

       -s     Instead of copying missing auxiliary files, install
              symbolic links.

       --localdir=dir

       -l dir Look  for  the package file aclocal.m4 in directory
              dir instead of in the current directory.

       --autoconf-dir=dir

       -m dir Look for the installed  macro  files  in  directory
              dir.   You can also set the AC_MACRODIR environment
              variable to a directory; this option overrides  the
              environment variable.

       --m4dir=dir

       -M dir Specify  location  of additional macro files (m4 by
              default).

       --cygnus

       --foreign

       --gnits

       --gnu

       --include-deps
              These options are recognized and passed through  to
              automake.
