Subject: Re: how to raise warning?

Hi!

* Robert Klemme:
> warn "#{__FILE__}:#{__LINE__}: there is an error"

If it is an error it raises an exception. A warning is used when
there is doubt wether something is wanted:

warn "#{__FILE__}:#{__LINE__}: no config file, using defaults"

As a rule of thumb a warning can be replaced by an 'Are you sure?' 
dialog.
