5214082SdimRead command-line options from @var{file}.  The options read are
6214082Sdiminserted in place of the original @@@var{file} option.  If @var{file}
7214082Sdimdoes not exist, or cannot be read, then the option will be treated
8214082Sdimliterally, and not removed.

10214082SdimOptions in @var{file} are separated by whitespace.  A whitespace
11214082Sdimcharacter may be included in an option by surrounding the entire
12214082Sdimoption in either single or double quotes.  Any character (including a
13214082Sdimbackslash) may be included by prefixing the character to be included
14214082Sdimwith a backslash.  The @var{file} may itself contain additional
15214082Sdim@@@var{file} options; any such options will be processed recursively.
