Grammar checker?

Is there some sort of grammar checking tool lying around
out there that will take a short, clear description of
my grammar (and I don't mean yacc squiggles!) like


    S -> Ex
    EX -> Te E1
    ...
    Te -> "a"


and tell me if it has LL or LR or LALR or SLR or ...
properties? Maybe with little messages like :
shift-reduce conflict in State 17
and a printout map of the states?


Yes, I know, I could do it by hand, but I'm lazy. We
used to have a thing like that at Norsk Data (well, okay,
the description was not that short and clear, but anyway)
for the old SINTRAN operating system. I'd like a
pointer to the name of such a beast for SUN 3 or 4, so
I can ask archie where to find it!


Thanks,

[I'd think a simple way to see if a grammar is LALR would be an awk script
to translate your favorite input syntax into yacc, followed by running the
result through yacc. -John]
