Exactly ... stage the deletes somewhere like ${HOME}/temp_delete and, if 
everything looks ok do a simple rm -rf ...

There is an easier way :-) Preserve the path underneath the temp root... 
something like:


  def delete_to_stage(file)
    destdir = File.join(TEMPROOT, File.dirname(file))
    FileUtils::mkdir_p(destdir)
    FileUtils::mv(file, destdir)
  end

Then you know exactly where things go back if need be...

Cheers,
Tim
