I hate to be nitpicky, but this slurps in File::Basename (9Kbytes) only to shorten the displayed command name.

I personally do not like programs that shorten $0 (or in C argv[0]) when they identify themselves. This is probably just me, but I was bitten by such programs too many times while debugging them, after wasting too many hours only to find that I was not running the executable I thought I was running but something else that happened to be earlier on my PATH X-<.
