 Using `autoscan' to Create `configure.ac'
 =========================================
 
    The `autoscan' program can help you create and/or maintain a
 `configure.ac' file for a software package.  `autoscan' examines source
 files in the directory tree rooted at a directory given as a command
 line argument, or the current directory if none is given.  It searches
 the source files for common portability problems and creates a file
 `configure.scan' which is a preliminary `configure.ac' for that
 package, and checks a possibly existing `configure.ac' for completeness.
 
    When using `autoscan' to create a `configure.ac', you should
 manually examine `configure.scan' before renaming it to `configure.ac';
 it will probably need some adjustments.  Occasionally, `autoscan'
 outputs a macro in the wrong order relative to another macro, so that
 `autoconf' produces a warning; you need to move such macros manually.
 Also, if you want the package to use a configuration header file, you
 must add a call to `AC_CONFIG_HEADERS' ( Configuration Headers).
 You might also have to change or add some `#if' directives to your
 program in order to make it work with Autoconf ( ifnames
 Invocation, for information about a program that can help with that
 job).
 
    When using `autoscan' to maintain a `configure.ac', simply consider
 adding its suggestions.  The file `autoscan.log' will contain detailed
 information on why a macro is requested.
 
    `autoscan' uses several data files (installed along with Autoconf)
 to determine which macros to output when it finds particular symbols in
 a package's source files.  These data files all have the same format:
 each line consists of a symbol, whitespace, and the Autoconf macro to
 output if that symbol is encountered.  Lines starting with `#' are
 comments.
 
    `autoscan' accepts the following options:
 
 `--help'
 `-h'
      Print a summary of the command line options and exit.
 
 `--version'
 `-V'
      Print the version number of Autoconf and exit.
 
 `--verbose'
 `-v'
      Print the names of the files it examines and the potentially
      interesting symbols it finds in them.  This output can be
      voluminous.
 
 `--include=DIR'
 `-I DIR'
      Append DIR to the include path.  Multiple invocations accumulate.
 
 `--prepend-include=DIR'
 
 `-B DIR'
      Prepend DIR to the include path.  Multiple invocations accumulate.
