How polished do tools need to be?

[Alan Bateman]

friday-stats is a great idea!!

So I'm curious how "polished" tools need to be? The initial tools that 
Jon pushed are really nice, ready to use with any CI system.

I have a several scripts that that I use to get interesting data and I'm 
wondering whether to clean them up. For example, I have a script that 
runs over the jtreg work directory to get print out the 50 slowest tests 
(I'm pretty sure Jon has a script for that one). Another one is a script 
that summarizes the ProblemList.txt to give the count of excluded tests 
by platform. Some of these might be too trivial but I find them useful.
