Great! I like this.

I've never used Tie before actually, so this is good sample code for me.

Why not "\n%\n" ? Because I coded that in about 3 nanoseconds, and it didn't even occur to me. Maybe some C oriented portion of my brain baulked at using more than one character as a separator?!

I think I had a reason for using /dev/urandom instead of rand. Who wants to remind me what it was? I've forgotten.
