+define Package/ucode-mod-mosquitto/description
+Native ucode C module wrapping libmosquitto with uloop integration.
+Provides full MQTT v3.1.1 client support including QoS 0/1/2, will messages,
+authentication and manual reconnect via the on_disconnect callback. TLS is
+available when the libmosquitto-ssl variant is selected; calling tls_set()
+against libmosquitto-nossl returns a runtime error. Scripts must call
+client.destroy() when finished, analogous to the cancel() requirement on
+ucode's uloop.timer.
