Hi all,

this is an important issue I was already thinking to add to TODO.
Currently there is no consistency. It could be added easily to
make the module ask: "may I overwrite?" - But: In script mode
we don't want such questions (or every module needs *another* parameter
to allow silent overwriting).

I am not sure what we want:
- change modules to ask for overwriting in both interactive and command line
  mode
- change modules to ask for overwriting in interactive mode, but silently
  overwrite in command line mode

Comment are welcome,

 Markus
