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.
