# hline

`hline` is a very small command line utility designed to highlight lines in log files. In practice, I've found that tuning the context that `grep` gives me when `tail -f`ing a log can be quite cumbersome. Oftentimes, all I really care about is seeing that a certain message happened and some surrounding context. `hline` fills that niche!
