You can supply all or part of the command line as a response file, which is an ASCII text file containing options for the command. You give the name of the response file on the command line, preceded by an at character (@). This name is replaced in the command by the contents of the file. Within the response file, the end of a line is equivalent to a comma separating filenames or a space between directives beyond the last comma.
The maximum length of a line in a response file is 256 characters.
Response files must not refer to other response files.
