45 | |
46 | In \`extract' mode (-x, default), extracts chunks named on standard input |
47 | from the list of libraries, and writes the result to standard output. |
48 | |
49 | In \`list' mode (-l), lists the chunks defined in the text libraries given. |
50 | |
51 | Options: |
52 | |
53 | -h, --help Print this help text. |
54 | -v, --version Print the program's version number. |
55 | -l, --list List chunks defined in text libraries. |
56 | -x, --extract Extract chunks from text libraries (default). |
57 | -o, --output=FILE Extract chunks to FILE, not standard output. |
