        longDescription = ''
          sdbus-c++ is a high-level C++ D-Bus library for Linux designed to provide
          expressive, easy-to-use API in modern C++.
          It adds another layer of abstraction on top of sd-bus, a nice, fresh C
          D-Bus implementation by systemd.
          It's been written primarily as a replacement of dbus-c++, which currently
          suffers from a number of (unresolved) bugs, concurrency issues and
          inherent design complexities and limitations.
