It's linked by their readme, but I've been using a similar command line tool, Bro (http://bropages.org/), for years and am very happy with it. The fact that Bro supports adding new entries (and upvoting the ones you find useful) directly from the command line has made me 100x more likely to contribute myself. (The fact that this project requires a GitHub pull request is a major barrier in this respect.)
Wow these bropages are just amazing. I read about it on HN but then totally forgot about it. Just tried it again now, it's just wonderful. I think I learned a lot of useful `sed` just by looking at those examples only. Great share, thanks!
