  * Attica ProviderManager
  *
  * This class is the primary access to Attica's functions.
  * Use the ProviderManager to load Open Collaboration Service providers,
  * either the default system ones, or from XML or custom locations.
  *
  * \section providerfiles Provider Files
  * Provider files are defined here:
  * http://www.freedesktop.org/wiki/Specifications/open-collaboration-services
  *
  * \section basicuse Basic Use
  *
  * See addProviderFileToDefaultProviders(const QUrl &url) for an example of
  * what the provider file sohuld look like. You can add providers to the
  * ProviderManager as either raw XML data using addProviderFromXml(const QString &providerXml),
  * or from a file somewhere on the system through addProviderFile(const QUrl &file),
  * or you can simply load the default providers provided by your system
  * (which generally means KDE's provider opendesktop.org).
  *
  * Importantly, to be able to detect when the ProviderManager is ready to
  * manage things, before initialising it you will want to connect to the
  * providerAdded(const Attica::Provider &provider) signal, which is fired
  * every time a new provider is added to the manager.
  *
  * If you manually add all providers from XML, you can expect this to happen
  * immediately. This means that once you have added your providers that way,
  * you can access them through the providers() function, which returns
  * a list of all loaded Providers.
  *
  * Once you have loaded a Provider, you can use its functions to access the
  * services offered by that provider.
