       autoreconf2.13 - update configure scripts


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


       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 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:


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


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


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


       -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.

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

              Print the version number of Autoconf and exit.
