The best thing about it is that it works. The displayed results are clear. It takes a little time to learn how to enter the rules of grammar, but I admit that I did not read the instructions and was able to make it work for me. I used it to help me write my own parser of my small grammar, and I learned a lot about LR parsers in the process. It is a little touchy about how you use spaces and does not process the terminal symbol (") well but I did not try to use (\") to see if this would botter. Overall, I loved it!
