Hey, I never said you *have* to do this compression!

I envisioned it as an option. I'd like, for example, to be able to aim a
program that the last eight weeks worth of log files and say, "compress
the first seven weeks of this, but leave the last week fully intact."
Then I can save some space (quite a lot, if my updates have certain
characteristics), and yet still get back to Tuesday evening at 7:59 p.m.
