This specifies the output filename to write parameters to or standard output if

this option is not specified.
|
|
The output filename can be the same as the input filename,
|
|
which leads to replacing the file contents.

Note that file I/O is not atomic. The output file is truncated and then written.

|
|
Do not output the encoded version of the parameters.
