+/**
+ * e_source_util_remote_delete:
+ * @source: an #ESource
+ * @alert_sink: an #EAlertSink
+ *
+ * Deletes the resource represented by @source from a remote server.
+ * The @source must be #ESource:remote-deletable.  This will also delete
+ * the key file for @source and broadcast its removal to all clients,
+ * similar to e_source_util_remove().  If an error occurs, an #EAlert
+ * will be posted to @alert_sink.
+ *
+ * This function does not block.  The returned #EActivity can either be
+ * ignored or passed to something that can display activity status to the
+ * user, such as e_shell_backend_add_activity().
+ *
+ * Returns: an #EActivity to track the operation
+ **/
