Yahoo data access

["cwest" <cwest@xxxxxxxxxxxx>]

http://finance.yahoo.com provides (free) access to stock prices although
I can't find a (yahoo) page that explains all of the arguments that you
can POST in an Action to retrieve data. Alex M. has some examples on his
website, but I don't know if they're complete. If anyone knows of a url
that covers yahoo's specs I'd appreciate them sending it to me.

Of course one can play with strings like the following to get data, but
specs would be "good."

msft&q=q&x=.csv&y=0&z=data

Thanks in advance
