httplog is a great tool - significantly more flexible than Apache's rotatelogs and very easy to install and configure.
autoconf configure script
Anyone willing to 'donate' an autoconf configure script thingy (and related other thingies to make it all work)? I have no idea how to work that stuff, and even though there's not much to really check for, it would be nice to have.
Email me if you would like to help!
