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.
