 2.4 Using `autoconf' to Create `configure'
 ==========================================
 
 To create `configure' from `configure.in', run the `autoconf' program
 with no arguments.  `autoconf' processes `configure.in' with the `m4'
 macro processor, using the Autoconf macros.  If you give `autoconf' an
 argument, it reads that file instead of `configure.in' and writes the
 configuration script to the standard output instead of to `configure'.
 If you give `autoconf' the argument `-', it reads the standard input
 instead of `configure.in' and writes the configuration script on the
 standard output.
 
    The Autoconf macros are defined in several files.  Some of the files
 are distributed with Autoconf; `autoconf' reads them first.  Then it
 looks for the optional file `acsite.m4' in the directory that contains
 the distributed Autoconf macro files, and for the optional file
 `aclocal.m4' in the current directory.  Those files can contain your
 site's or the package's own Autoconf macro definitions ( Writing
 Macros, for more information).  If a macro is defined in more than
 one of the files that `autoconf' reads, the last definition it reads
 overrides the earlier ones.
 
    `autoconf' accepts the following options:
 
 `--help'
 `-h'
      Print a summary of the command line options and exit.
 
 `--localdir=DIR'
 `-l DIR'
      Look for the package file `aclocal.m4' in directory DIR instead of
      in the current directory.
 
 `--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.
