Subject: Error reporting in Racc

Hi

I think I finally have got a handle on parsing with
Racc, and let me say, this tool rocks.

However, I am having a little difficulty generating
human readable parse/syntax errors. I am using the #on_error
method, but all it receives are an internal symbol ID,
the symbol and part of the current stack.  

I am tracking line numbers, but often the parser fails
several lines after the symbol that it passes
to #on_error.

Is there some docs on how to create clear error messages
with Racc?

Thanks
