+ * @brief Experimental module to emulate tor_run_main() API with fork+exec
+ *
+ * The functions here are meant to allow the application developer to
+ * use the tor_run_main() API without having to care whether Tor is
+ * running in-process or out-of-process. For in-process usage, the
+ * developer can link Tor as a library and call tor_run_main(); for
+ * out-of-process usage, the developer can link this library instead.
+ *
+ * This interface is EXPERIMENTAL; please let us know if you would like
+ * to depend on it. We don't know yet whether it will be reliable in
+ * practice.
+ */
+
+/* NOTE: This module is supposed to work without the standard Tor utility
+ * functions. Don't add more dependencies!
