19 !!DESCRIPTION
20
21
22 The __autoscan2.13__ program can help you create a
23 __configure.in__ file for a software package.
24 __autoscan2.13__ examines source files in the directory
25 tree rooted at a directory given as a command line argument,
26 or the current directory if none is given. It searches the
27 source files for common portability problems and creates a
28 file __configure.scan__ which is a preliminary
29 __configure.in__ for that package.
30
31
32 You should manually examine __configure.scan__ before
33 renaming it to __configure.in__; it will probably need
34 some adjustments. Occasionally __autoscan2.13__ outputs a
35 macro in the wrong order relative to another macro, so that
36 __autoconf2.13__ produces a warning; you need to move
37 such macros manually. Also, if you want the package to use a
38 configuration header file, you must add a call to
39 __AC_CONFIG_HEADER__. You might also have to change or
40 add some __#if__ directives to your program in order to
3 perry 41 make it work with Autoconf (see ifnames2.13(1)), for
1 perry 42 information about a program that can help with that
43 job).
44
45
46 __autoscan2.13__ uses several data files, which are
47 installed along with the distributed Autoconf macro files,
48 to determine which macros to output when it finds particular
49 symbols in a package's source files. These files all have
50 the same format. Each line consists of a symbol, whitespace,
51 and the Autoconf macro to output if that symbol is
52 encountered. Lines starting with __#__ are
53 comments.
54
55
56 __autoscan2.13__ requires that a Perl interpreter is
57 installed.
58
59
60 __autoscan2.13__ accepts the following
61 options:
62
63
64 __--help__
65
66
67 __-h__
68
69
70 Print a summary of the command line options and
71 exit.
72
73
74 __--macrodir=DIR__
75
76
77 __-m DIR__
78
79
80 Look for the installed macro files in directory DIR. You can
81 also set the __AC_MACRODIR__ environment variable to a
82 directory; this option overrides the environment
83 variable.
84
85
86 __--verbose__
87
88
89 Print the names of the fiels it examines and the potentially
90 interesting symbols it finds in them. This output can be
91 voluminous.
92
93
94 __--version__
95
96
97 Print the version number of Autoconf and exit.
