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.

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.

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.

Thanks!
