If present this line makes the extension run independently from KStars. Once it has been started the extension can not pass status information back to Ekos. This should only be used by extensions that are required to continue to run after KStars has closed. The extension must also provide it's own user interface.

       Extensions that are present, have a valid configuration file, and have a minimum KStars version no higher than the current installation will be detected when Ekos is started. If there are no valid extensions detected the extension UI element will not be displayed. The extension UI elements are a ComboBox showing the name and icon of each detected extension, and a start/stop button. If the extension fails to close within 10 seconds of the stop button being clicked, it becomes re-enabled as an abort button that will force close the extension. Only one extension can be used at a time.

             It may appear on initial investigation that using the Qt DBus Adaptors system would be much easier than direct use of the Qt DBus Interfaces/Messages and KStars does provide the required xml definitions. However currently there is heavy use of custom types the definitions of which are combined with other information in the KStars sources. This results in a large set of files from KStars that require inclusion within an extension in order to make use of the Qt DBus Adaptors. Hopefully this will be addressed in the future.
