How do I obtain historical stock information from yahoo finance via javascript?

Hi everyone,
I'm new to Yahoo Finance since google decided to ditch its finance APIs. I have a google spreadsheet script (javascript) that I'd like to use to collect data historical stock data from yahoo finance, but I know absolutely nothing about YQL, YDN, or any other yahoo-related acronyms.

So my understanding (please correct me if I'm wrong) is that historical stock data cannot be collected via YQL queries, and I have to use some sort of html query string. That's fine, but I have not been able to find any documentation on how to construct these queries (I've seen a few examples online, but without documentation it's somewhat useless).

So if someone could a) give me a simple example of how I might be able to get historical daily price data starting at date X and finishing at date Y into a javascript array and b) tell me where I might find documentation about what options I can modify in the query (historic price between dates, volumes, stock symbol, etc.).

I'm very grateful for your help in advance! Thanks.
