  53 Usage: mkaclocal [-lx] [-c CONFIG] [-o OUTPUT] [LIBRARY...]
  54
  55 In \`extract' mode (-x, default), constructs an \`aclocal.m4' file containing
  56 the right macros for the \`configure.in' script CONFIG (by default this is
  57 \`configure.in').  The output is written to OUTPUT, or \`aclocal.m4' if none
  58 was specified.
  59
  60 In addition to libraries specified on the command line, the files
  61 \`aclocal.glob' and \`aclocal.site' contained in the shared file repository,
  62 and \`aclocal.lib' in the current directory are also searched.
  63
  64 If \`aclocal.lib' contains the string \`*@--TOP--@*', the preceding text is
  65 written at the top of any output file generated.
  66
  67 In \`list' mode (-l), lists the macros defined in the various libraries.
  68
  69 Options:
  70
  71 -h, --help              Print this help text.
  72 -v, --version           Print the program's version number.
  73 -l, --list              List chunks defined in text libraries.
  74 -x, --extract           Extract chunks from text libraries (default).
  75 -n, --no-stdlib         Don't read from the standard libraries.
  76 -c, --config=CONFIG     Read CONFIG, not \`configure.in', to decide which
  77                         macros need extracting.
  78 -o, --output=OUTPUT     Extract chunks to OUTPUT, not \`aclocal.m4'.
