| 5 | Read command-line options from @var{file}. The options read are |
| 6 | inserted in place of the original @@@var{file} option. If @var{file} |
| 7 | does not exist, or cannot be read, then the option will be treated |
| 8 | literally, and not removed. |
| 9 | |
| 10 | Options in @var{file} are separated by whitespace. A whitespace |
| 11 | character may be included in an option by surrounding the entire |
| 12 | option in either single or double quotes. Any character (including a |
| 13 | backslash) may be included by prefixing the character to be included |
| 14 | with a backslash. The @var{file} may itself contain additional |
| 15 | @@@var{file} options; any such options will be processed recursively. |
