60 Run `autoconf' (and `autoheader', `aclocal', `automake', `autopoint'
61 (formerly `gettextize'), and `libtoolize' where appropriate)
62 repeatedly to remake the GNU Build System files in specified
63 DIRECTORIES and their subdirectories (defaulting to `.').
65 By default, it only remakes those files that are older than their
66 sources. If you install new versions of the GNU Build System,
67 you can make `autoreconf' remake all of the files by giving it the
68 `--force' option.
70 Operation modes:
71 -h, --help print this help, then exit
72 -V, --version print version number, then exit
73 -v, --verbose verbosely report processing
74 -d, --debug don't remove temporary files
75 -f, --force consider all files obsolete
76 -i, --install copy missing auxiliary files
77 --no-recursive don't rebuild sub-packages
78 -s, --symlink with -i, install symbolic links instead of copies
79 -m, --make when applicable, re-run ./configure && make
80 -W, --warnings=CATEGORY report the warnings falling in CATEGORY [syntax]
82 " . Autom4te::ChannelDefs::usage . "
84 The environment variable \`WARNINGS\' is honored. Some subtools might
85 support other warning types, using \`all' is encouraged.
87 Library directories:
88 -B, --prepend-include=DIR prepend directory DIR to search path
89 -I, --include=DIR append directory DIR to search path
91 The environment variables AUTOCONF, AUTOHEADER, AUTOMAKE, ACLOCAL,
92 AUTOPOINT, LIBTOOLIZE, M4 are honored.
94 Report bugs to <bug-autoconf\@gnu.org>.
