+@c This file is designed to be included in manuals that use 
+@c expandargv.
+
+@item @@@var{file}
+Read command-line options from @var{file}.  The options read are
+inserted in place of the original @@@var{file} option.  If @var{file}
+does not exist, or cannot be read, then the option will be treated
+literally, and not removed.  
+
+Options in @var{file} are separated by whitespace.  A whitespace
+character may be included in an option by surrounding the entire
+option in either single or double quotes.  Any character (including a
+backslash) may be included by prefixing the character to be included
+with a backslash.  The @var{file} may itself contain additional
+@@@var{file} options; any such options will be processed recursively.
