AUTOUPDATE(E)                                       AUTOUPDATE(E)



NAME
       autoupdate2.13  - updates an old configure.in file to ver-
       sion 2

SYNOPSIS
       autoconf2.13 [ --help | -h ] [ --macrodir=dir | -m dir ] [
       --version ]

DESCRIPTION
       The  autoupdate2.13  program  updates  a configure.in file
       that calls Autoconf macros by their old names to  use  the
       current  macro  names.   In version 2 of Autoconf, most of
       the macros were renamed to use a more uniform and descrip-
       tive  naming  scheme.  Although the old names still work ,
       you can make your configure.in  files  more  readable  and
       make  it  easier to use the current Autoconf documentation
       if you update them to use the new macro names.   If  given
       no arguments, autoupdate2.13 updates configure.in, backing
       up the original version with the suffix ~ (or the value of
       the  environment variable SIMPLE_BACKUP_SUFFIX, if that is
       set).  If you give autoupdate2.13 an  argument,  it  reads
       that  file  instead of configure.in and writes the updated
       file to the standard output.

       autoconf2.13 accepts the following options:

       --help

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

       --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.

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