The Story

Really simple, but handy to have around.

While spending some time in the #redhat support channel on irc.freenode.net, one day someone asked if I could create this little util during discussions over the tailfilter program. I quickly cranked it out and tweaked it into shape for him. Should you find it useful, feel free to grab it. :-)
