nothing - does nothing
Last April 4, I submitted a program called "nothing", which does just that: nothing. The description was a commentary on how too much useless software gets posted on Freshmeat. Apparently, the Freshmeat editors didn't share either my concern or my sense of humor, and it never got posted. See http://osiris.978.org/~brianr/nothing/. I'm glad to see that trivial submissions are finally being rejected.
