Hi Ben,

Additionally, we are trying to open source a graphical tool we have 
developed, called GChisto, that can show you a lot of stats about your 
log, as well as other interesting graphs. We have been using it to 
analyze customer logs and it has been very helpful. Once we have the OK 
to open source it, we'll announce it on this list.
