+ * lib should only depend on QtCore >=5.3, possibly boost::python
  * common functions like partitioning
  * works as job queue and executor
  * plugin based to bet distro-specific tasks done in a distro-specific order
 * Frontend
+ * QtWidgets >=5.3, other deps as needed
  * themeable so branding can be done easily (plugin-based)
