> In some cases, especially when a streaming command is a 3rd party or legacy application, 
> it is impossible of inconvenient to make it take its input from stdin.
> The command may require that the input file name is specified as a command line option, or the input file name is hard coded.
> The streaming infrastructure should allow to specify a name that can be used in open() to create an input stream equivalent to what would be fed to a streaming command as stdin by default.
