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.
