  50 Usage: mkaclocal [-lx] [-c CONFIG] [-o OUTPUT] [LIBRARY...]
  51
  52 In \`extract' mode (-x, default), constructs an \`aclocal.m4' file containing
  53 the right macros for the \`configure.in' script CONFIG (by default this is
  54 \`configure.in').  The output is written to OUTPUT, or \`aclocal.m4' if none
  55 was specified.
  56
  57 In addition to libraries specified on the command line, the files
  58 \`aclocal.glob' and \`aclocal.site' contained in the shared file repository,
  59 and \`aclocal.lib' in the current directory are also searched.
  60
  61 If \`aclocal.lib' contains the string \`*@--TOP--@*', the preceding text is
  62 written at the top of any output file generated.
  63
  64 In \`list' mode (-l), lists the macros defined in the various libraries.
  65
  66 Options:
  67
  68 -h, --help              Print this help text.
  69 -v, --version           Print the program's version number.
  70 -l, --list              List chunks defined in text libraries.
  71 -x, --extract           Extract chunks from text libraries (default).
  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'.
