  62 Usage: txtlib [-lx] [-o FILE] [LIBRARY...]
  63
  64 In \`extract' mode (-x, default), extracts chunks named on standard input
  65 from the list of libraries, and writes the result to standard output.
  66
  67 In \`list' mode (-l), lists the chunks defined in the text libraries given.
  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 -o, --output=FILE       Extract chunks to FILE, not standard output.
