       autoscan2.13  -  help  to  create  a  file for a software


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


       The autoscan2.13 program can help you create a 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 for that package.

       You  should  manually  examine  configure.scan  before  renaming  it to; 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:


       -h     Print a summary of the command line options and exit.


       -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.

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

              Print the version number of Autoconf and exit.
