Update: other ways to do the same thing

ajt /msg'd me to say that www.analog.cx gives away a fully-featured log analyser - and indeed they do. It looks very good and I shall upgrade to it when / if traffic on my sites warrants.

jryan has written a slightly specialised log analyser with an interesting take on sorting the entries, which instead of placing in the code catacombs he has modestly hidden here.

I'll add other such links here as they come in... as no doubt they will :)
