  49 Usage: mkaclocal [-lx] [-c CONFIG] [-o OUTPUT] [LIBRARY...]
  50
  51 In \`extract' mode (-x, default), constructs an \`aclocal.m4' file containing
  52 the right macros for the \`configure.in' script CONFIG (by default this is
  53 \`configure.in').  The output is written to OUTPUT, or \`aclocal.m4' if none
  54 was specified.
  55
  56 In addition to libraries specified on the command line, the files
  57 \`aclocal.glob' and \`aclocal.site' contained in the shared file repository,
  58 and \`aclocal.lib' in the current directory are also searched.
  59
  60 If \`aclocal.lib' contains the string \`*@--TOP--@*', the preceding text is
  61 written at the top of any output file generated.
  62
  63 In \`list' mode (-l), lists the macros defined in the various libraries.
  64
  65 Options:
  66
  67 -h, --help              Print this help text.
  68 -v, --version           Print the program's version number.
  69 -l, --list              List chunks defined in text libraries.
  70 -x, --extract           Extract chunks from text libraries (default).
  71 -n, --no-stdlib         Don't read from the standard libraries.
  72 -c, --config=CONFIG     Read CONFIG, not \`configure.in', to decide which
  73                         macros need extracting.
  74 -o, --output=OUTPUT     Extract chunks to OUTPUT, not \`aclocal.m4'.
