+/**
+ * @brief Template based, single file, wrapper library around eldbus for DBUS based communication.
+ *
+ * Main motivation was missing asynchronous calls in AT-SPI library and difficulties,
+ * when using eldbus from C++.
+ *
+ * The library:
+ * - takes care of marshalling arguments to and from DBUS calls.
+ * - allows synchronous and asynchronous calls.
+ * - allows synchronous and asynchronous listeners on signals.
+ * - manages all involved objects' lifetimes.
+ * - errors are passed as optional-alike objects, no exceptions are used.
+ * - allows setting additional debug-print function for more details about
+ * what's going on
+ *
+ * DBUS's method signatures (and expected return values) are specified as template argument,
+ * using functor syntax. For example:
+ * \code{.cpp}
+ * auto dbus = DBusClient{ ... };
+ * auto v = dbus.method<std::tuple<int, float>(float, float, std::string)>("foo").call(1.0f, 2.0f, "qwe");
+ * \endcode
+ * means (synchronous) call on dbus object, which takes three arguments (thus making call signature \b dds)
+ * of types float, float and string (float will be automatically converted to double).
+ * Expected return value is std::tuple<int, float>, which gives signature <B>(id)</B> - std::tuple acts
+ * as struct container. Returned value v will be of type ValueOrError<std::tuple<int, float>>.\n
+ * Slightly different (asynchronous) example:
+ * \code{.cpp}
+ * auto dbus = DBusClient{ ... };
+ * std::function<void(ValueOrError<int, float>)> callback;
+ * dbus.method<ValueOrError<int, float>(float, float, std::string)>("foo").asyncCall(callback, 1.0f, 2.0f, "qwe");
+ * \endcode
+ * Now the call takes the same arguments and has the same signature. But expected values are different -
+ * now the signature is simply \b id. ValueOrError acts in this case as placeholder for list of values,
+ * which DBUS allows as return data. The call itself is asynchronous - instead of expecting reply
+ * you need to pass a callback, which will be called either with received data and error message.
+ *
+ * Library is not thread-safe, the same object shouldn't be called from different threads without
+ * synchronization. There's no guarantee, that callbacks will be executed on the same thread.
