 Upgrading From Version 2.13
 ===========================
 
    The introduction of the previous section ( Autoconf 1)
 perfectly suits this section....
 
      Autoconf version 2.50 is mostly backward compatible with version
      2.13.  However, it introduces better ways to do some things, and
      doesn't support some of the ugly things in version 2.13.  So,
      depending on how sophisticated your `configure.ac' files are, you
      might have to do some manual work in order to upgrade to version
      2.50.  This chapter points out some problems to watch for when
      upgrading.  Also, perhaps your `configure' scripts could benefit
      from some of the new features in version 2.50; the changes are
      summarized in the file `NEWS' in the Autoconf distribution.
