NAME

       autoscan2.13 - help to create a configure.in file for a software package

SYNOPSIS

       autoscan2.13 [ --help ] [ --macrodir=dir ] [ --verbose ] [ --version ]

DESCRIPTION

       The  autoscan2.13  program can help you create a configure.in file for a software package.
       autoscan2.13 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.in for that package.

       You  should  manually  examine  configure.scan before renaming it to configure.in; it will
       probably need some adjustments.  Occasionally autoscan2.13 outputs a macro  in  the  wrong
       order relative to another macro, so that autoconf2.13 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_HEADER.  You might also have to change or add some #if
       directives to your program in order to make it work with  Autoconf  (see  ifnames2.13(1)),
       for information about a program that can help with that job).

       autoscan2.13  uses  several  data  files,  which  are installed along with the distributed
       Autoconf macro files, to determine which macros to output when it finds particular symbols
       in a package's source files.  These 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.

       autoscan2.13 requires that a Perl interpreter is installed.

       autoscan2.13 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.

       --verbose
              Print the names of the fiels it examines and the potentially interesting symbols it
              finds in them.  This output can be voluminous.

       --version
              Print the version number of Autoconf and exit.
