+This sample demonstrates basic usage of the FoundryLocalClient.

+Running this sample the first time will be slow, as the model needs to be
+downloaded and initialized.
+
+Also, not every model supports function calling, so be sure to check the
+model capabilities in the Foundry catalog, or pick one from the list printed
+when running this sample.
