Hi all,

I pulled the following message from the website text search. I find it
hard to follow the example in the message though, and wonder if anyone
can further explain why Earley's parsing extension to his recognizer
algorithm given in his Ph.D. thesis does not correctly build parse
trees. Any examples or references to papers would be appreciated. Thanks.
