AUTOCONF(1)                                                        AUTOCONF(1)

NAME
       autoscan2.13  - help to create a configure.in file for a software pack-
       age

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 con-
       figure.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 out-
       put  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 encoun-
       tered.  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 volu-
              minous.

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