+ * In addition to the three APIs described above Avahi supports two
+ * compatibility libraries:
+ *
+ * \li avahi-compat-libdns_sd: the original Bonjour API as documented
+ * in the header file "dns_sd.h" by Apple Computer, Inc.
+ *
+ * \li avahi-compat-howl: the HOWL API as released with HOWL 0.9.8 by
+ * Porchdog Software.
+ *
+ * Please note that these compatibility layers are incomplete and
+ * generally a waste of resources. We strongly encourage everyone to
+ * use our native APIs for newly written programs and to port older
+ * programs to one of them!
