You may see the results while they are still there:<br>

I found one of the problems with generated rail road diagrams is
that they are often too low level, making it hard for them to be
useful. They often splits things up into too small a pieces, as they
are a literal translation of the grammar and not a logical
representation for end users. That said it, it's probably better to
have well maintained generated versinos, than out of date hand
created ones. Just a shame there isn't a tool that allows for easy
hand editing of rail raod diagrams.<br>

I think part of the problem is caused by the lack of consistency in
our grammar for exressions - evals, return values etc. Edson is
working on that so we have a generic and clean grammar for
expressions, this should add more regularity to our grammar.<br>
