You can use response files to:
Specify options used during particular compilations for particular projects
Save this information in individual files
Unlike configuration files, which are automatically processed every time you run the compiler, response files must be invoked as an option on the command line. If you create a response file but do not specify it on the command line, it will not be invoked.
Options specified in a response file are inserted in the command line at the point where the response file is invoked.
You can place any number of options or filenames on a line in the response file. Several response files can be referenced in the same command line.
The syntax for using response files is:
ifort @responsefile1 [@responsefile2 ... ]
An "at" sign (@) must precede the name of the response file on the command line.
