/**
* @class ServiceJob plasma/servicejob.h <Plasma/ServiceJob>
*
* @short This class provides jobs for use with Plasma::Service
*
* Unlike KJob, you can do the work in start(), since Plasma::Service already
* delays the call to start() until the event loop is reached.
*
* If the job is quick enough that it is not worth reporting the progress,
* you just need to implement start() to do the task, then call emitResult()
* at the end of it. If the task does not complete successfully, you should
* set a non-zero error code with setError(int) and an error message with
* setErrorText(QString).
*
* If the job is longer (involving network access, for instance), you should
* report the progress at regular intervals. See the KJob documentation for
* information on how to do this.
