@-files

Users sometimes run into system limitations on the length of a command line when creating a command line with lots of options or with long arguments for options for a specific tool.

Tools for which this is a common problem may choose to support "argument files" or "@-files", containing strings to be expanded in place of the @file argument. Tools are encouraged to support the same syntax for the tokens within such an argument file.
