Are there any tutorials on creating a client in Ruby for RESTful Rails app?

Hi,

I got a REStful Rails app and would like to create a simple command
line app (probably later with a GUI) to display/manage data from the
Rails app.

There are bilions of tutorials/presentation on writing RESTful Rails
apps, but are there any tutorials how to write simple clients? I.e.
parsing data from Rails app, how to do authentication (I'm using
restful_authentication plugin), error handling etc? It's nothing very
complicated, but some examples, tips would be really useful.

Regards

Hey, blinksale.com does a great job explaining how they use their API with the cURL command-line program. Maybe that would get you going in the right direction. www.blinksale.com/api explains a lton of stuff.
