I would like access to the switches, printing is irrespective. However, if it is of importance then STDOUT is a good place for it.

cat was purely meant as an FYI to suggest that I did look in @ARGV before posting. In fact dare I say, it also suggests STDOUT, (negat|answer)ing your first question.

The code will be executed by other people, and they might put any number of perl switches in on the command line which I would like to be able to determine.
