This library was designed to make it easier to access web services that claim to be "RESTful". A RESTful service should have urls that represent remote objects, which methods can then be called on. The majority of services don't actually adhere to this strict definition. Instead, their RESTful end point usually has an API that is just simpler to use compared to other types of APIs they may support (XML-RPC, for instance). It is this kind of API that this library is attempting to support.
