While we are in the dream features, I would also like to see a way to 
pass a format string to the program to choose how the output is 
formatted (like the "date" program). For example "%t : %c, %e" to output 
"timestamp : channel, event". That way the output would suit everyone's 
need and specific parsers could be implemented on top of that.
