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.
