I had a problem at work which required finding certain patterns in our log files. I figured that someone had built such a think (at least at a large log analysis company like Splunk), but I couldn't find anything.<p>I'm not sure how common of a problem this is for people, but I figured I'd try to build something to see if my solution even made sense. It turns out it works quite well.<p>Have you heard of problems this could solve, or projects like this? Please let me know! I put some decent effort into documenting the tool, but tell me if it's unclear.<p>Thanks!
