It is a rejoinder. The follow up is:

Oi!

Oi is for 'orses


Sorry, I can only remember primary school jokes. ;-)

Might something like this be implemented as an INI file option?  Perhaps 
to rename the file (including date and time) at the end of the render, 
or possibly to make a backup copy?  The concept strikes me as rather 
INI-ish.

Just a couple of insomniac thoughts...

Post-frame shell-out (`Post_Frame_Command=...`) should be able to do
this. It would be specific to a particular operating system though.

It should also be possible to use pre-frame shell-out
(`Pre_Frame_Command`) to back up an existing file of the same name.
