Log analysis software

[Stacy Pober]

I'm looking for a log analyzer for Apache style server logs.  WebTrends
seems to only be available now as an expensive suite that contains a lot
of functionality I just don't need.  

Is there an 'unbundled' log analyzer available from them or from another
software producer that would do the job?  I'm looking for something that
is relatively painless to learn, in so far as that's possible.
