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