  58 Run `autoconf' (and `autoheader', `aclocal', `automake', `autopoint'
  59 (formerly `gettextize'), and `libtoolize' where appropriate)
  60 repeatedly to remake the GNU Build System files in specified
  61 DIRECTORIES and their subdirectories (defaulting to `.').
  62
  63 By default, it only remakes those files that are older than their
  64 sources.  If you install new versions of the GNU Build System,
  65 you can make `autoreconf' remake all of the files by giving it the
  66 `--force' option.
  67
  68 Operation modes:
  69   -h, --help               print this help, then exit
  70   -V, --version            print version number, then exit
  71   -v, --verbose            verbosely report processing
  72   -d, --debug              don't remove temporary files
  73   -f, --force              consider all files obsolete
  74   -i, --install            copy missing auxiliary files
  75       --no-recursive       don't rebuild sub-packages
  76   -s, --symlink            with -i, install symbolic links instead of copies
  77   -m, --make               when applicable, re-run ./configure && make
  78   -W, --warnings=CATEGORY  report the warnings falling in CATEGORY [syntax]
  79
  80 " . Autom4te::ChannelDefs::usage . "
  81
  82 The environment variable \`WARNINGS\' is honored.  Some subtools might
  83 support other warning types, using \`all' is encouraged.
  84
  85 Library directories:
  86   -B, --prepend-include=DIR  prepend directory DIR to search path
  87   -I, --include=DIR          append directory DIR to search path
  88
  89 The environment variables AUTOCONF, AUTOHEADER, AUTOMAKE, ACLOCAL,
  90 AUTOPOINT, LIBTOOLIZE, M4, and MAKE are honored.
