/** Bootstrap offers functionality to obtain a context or simply
  a service manager.
  The service manager can create a few basic services, whose implementations  are:
  <ul>
  <li>com.sun.star.comp.loader.JavaLoader</li>
  <li>com.sun.star.comp.urlresolver.UrlResolver</li>
  <li>com.sun.star.comp.bridgefactory.BridgeFactory</li>

  <li>com.sun.star.comp.connections.Acceptor</li>
  <li>com.sun.star.comp.servicemanager.ServiceManager</li>
  </ul>

  Other services can be inserted into the service manager by
  using its XSet interface:
  <pre>
    XSet xSet = (XSet)UnoRuntime.queryInterface( XSet.class, aMultiComponentFactory );
    // insert the service manager
    xSet.insert( aSingleComponentFactory );
