I've used it myself with a few forks and it did what it was supposed to do. There is another one (https://github.com/Ayms/bitcoin-transactions) but it takes a 1-2% fee or something. If you go our website http://findmycoins.ninja, after searching for your coins at the bottom there will be a "Full report" button where we crafted some of the commands for you. It's still in beta but you might find it useful.
