Many of Big Sister's features have been moved out of the core implemenation into plugins. During installation all of the commonly used plugins have been installed. You can upgrade existing plugins and install additional plugins via the
bsmodule
command. List the installed plugins with
bsmodule list
and install or upgrade modules with
bsmodule install [module-name]
The available plugins can be found on http://www.bigsister.ch/plugins.html. Unless you download the respective module file from there, bsmodule will automatically contact the software download server and try to download a module with the name you specified.
