Linode Ruby API

INSTALLATION:

 Make sure gemcutter.org is in your gem sources list, then:

 % sudo gem install linode

 To run tests you will need both rspec and mocha installed.

RUNNING:

 Consult the Linode API guide here:  http://www.linode.com/api/autodoc.cfm
 You will need to get an API key (check your account profile).

Here is an annoyingly exhaustive IRB session where I play around with the API:

 irb> result.baz

 irb> result = l.avail.datacenters
