+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.
