sportdb v2.0 - tool for reading datasets (leagues, clubs, matches, ...) into SQL DB

Hello, I’ve updated the sportdb command line tool / library that lets you read in (parse) datasets (e.g. leagues, clubs, match schedules, etc.) in plain text into your SQL database of choice (e.g. SQLite, PostgreSQL, etc.). For example, to build yourself a copy for the English Premier League 2019/20 season type: $ sportdb new eng2019-20. That’s all. This will read in the match schedule and much more from the /england dataset. Happy data and text wrangling with ruby. Enjoy the beautiful game. PS: See the football.db League Quick Starter Sample - Mauritius Premier League if you want to start from scratch (zero) with your very own league.
