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.
