counting number of rules in rule base


i am creating a large number of rewrite rules of the form symb[arg] = rhs

these rules are being generated automatically and i don't know how many
rules are created [in the case i'm dealing with it, its over 500].

without doing ?symb and then counting the number of rules that come up on
my monitor screen [i keep losing count around 125 or so], how can i ask
Mathematica for the number of rules associated with symb?

thanks.
