NAME

       autoupdate2.13 - updates an old configure.in file to version 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  descriptive  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.
