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.
