1 @c This file is designed to be included in manuals that use 2 @c expandargv. 3 4 @item @@@var{file} 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. 16
