Google spreadsheets - getting started

[Mark Carter]

I want to mess around with my online Google spreadsheets from my Linux box programmatically. I am TOTALLY confused.

I've got gdata installed, and it appears that the best way to access the spreadsheets is to authenticate with Oauth2.

Here's the main thing: how do I get an Oauth2 key to use with Google spreadsheets?

I obtain a "p12" key, but I don't know if that's for something completely different.
