As a sidenote, I always use the diamond operator magic in commandline tools. It has significant advantages: considering the scripts are usually short, getting all I/O dealt with in a single while(<>) is really convenient, and it deals with any number of files without me having to write an extra loop over @ARGV. I also have these scripts write any actual output to STDOUT and errors or other messages strictly to STDERR, so that the user can redirect or pipe the result (or just let it print to screen) at their convenience. And because these handles are given, I don't need to deal with opening output files either. Also since the diamond operator peeks at @ARGV at the time it is invoked, I can munge any commandline parameters with Getopt::* beforehand, and it works out beautifully.

Bottom line, I can have my cake and eat it too: a lot less code, and consequently work, but maximum flexibility. Perl rocks that way.
