Using GData API's from the command line

In a post entitled "cURLing - Not just for Canadians anymore!", Ryan Boyd of the Gogole Data APIs Team (I take it that should be "Google", but typos are so easily made), points to his recent tutorial as to how to use GData APIs using command line tools.

The major tool covered is cURL, and the chosen API used for the examples is the Picasa Web Albums data API.

The article also mentions other tools such as telnet, openssl, wget, and xsltproc. Using command line tools in this way is unlikely to have mainstream appeal - but it's invaluable for testing and developing purposes.
