  24
  25 Run \`autoconf' (and \`autoheader', \`aclocal' and \`automake', where
  26 appropriate) repeatedly to remake the Autoconf \`configure' scripts
  27 and configuration header templates in the directory tree rooted at the
  28 current directory.  By default, it only remakes those files that are
  29 older than their predecessors.  If you install a new version of
  30 Autoconf, running \`autoreconf' remakes all of the files by giving it
  31 the \`--force' option.
  32
  33 Operation modes:
  34   -h, --help      print this help, then exit
  35   -V, --version   print version number, then exit
  36   -v, --verbose   verbosely report processing
  37   -d, --debug     don't remove temporary files
  38   -f, --force     consider every files are obsolete
  39   -i, --install   copy missing auxiliary files
  40   -s, --symlink   instead of copying, install symbolic links
  41
  42 The option \`--install' is similar to the option \`--add-missing' in
  43 other tools.
  44
  45 Library directories:
  46   -A, --autoconf-dir=ACDIR  Autoconf's macro files location (rarely needed)
  47   -l, --localdir=DIR        location of \`aclocal.m4' and \`acconfig.h'
  48   -M, --m4dir=M4DIR         this package's Autoconf extensions
  49
  50 Unless specified, heuristics try to compute \`M4DIR' from the \`Makefile.am',
  51 or defaults to \`m4' if it exists.
  52
  53 The following options are passed to \`automake':
  54      --cygnus          assume program is part of Cygnus-style tree
  55      --foreign         set strictness to foreign
  56      --gnits           set strictness to gnits
  57      --gnu             set strictness to gnu
  58      --include-deps    include generated dependencies in Makefile.in
  59
  60 The environment variables AUTOCONF, AUTOHEADER, AUTOMAKE, and ACLOCAL
  61 are honored.
