NAME

       autoreconf2.13 - update configure scripts

SYNOPSIS

       autoreconf2.13 [ --help | -h ] [ --force | -f ] [ --localdir=dir | -l dir ] [ --macrodir=dir | -m dir ] [
       --verbose ] [ --version ]

DESCRIPTION

       If  you  have a lot of Autoconf-generated configure scripts, the autoreconf2.13 program can save you some
       work.  It runs autoconf2.13 (and autoheader2.13, where appropriate) repeatedly  to  remake  the  Autoconf
       configure  scripts  and  configuration  header  templates  in  the  directory  tree rooted at the current
       directory.  By default, it only remakes those files  that  are  older  than  their  configure.in  or  (if
       present)  aclocal.m4.   Since autoheader2.13 does not change the timestamp 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 autoreconf2.13 remake all of the files by giving it the --force option.

       If  you  give  autoreconf2.13  the  --macrodir=DIR  or  --localdir=DIR  options,  it  passes them down to
       autoconf2.13 and autoheader2.13 (with relative paths adjusted properly).

       autoreconf2.13 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 directory is a separate package, if you don't use it.  This restriction  may
       be removed in the future.

       autoreconf2.13 accepts the following options:

       --help

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

       --force

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

       --localdir=DIR

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

       --macrodir=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.

       --verbose
              Print the name of each directory where autoreconf2.13 runs autoconf2.13  (and  autoheader2.13,  if
              appropriate).

       --version
              Print the version number of Autoconf and exit.
