+ * YPSERV PROTOCOL:
+ *
+ * ypserv supports the following procedures:
+ *
+ * YPPROC_NULL takes (void), returns (void).
+ * called to check if server is alive.
+ * YPPROC_DOMAIN takes (char *), returns (bool_t).
+ * true if ypserv serves the named domain.
+ * YPPROC_DOMAIN_NOACK takes (char *), returns (bool_t).
+ * true if ypserv serves the named domain.
+ * used for broadcasts, does not ack if ypserv
+ * doesn't handle named domain.
+ * YPPROC_MATCH takes (struct ypreq_key), returns (struct ypresp_val)
+ * does a lookup.
+ * YPPROC_FIRST takes (struct ypreq_nokey) returns (ypresp_key_val).
+ * gets the first key/datum from the map.
+ * YPPROC_NEXT takes (struct ypreq_key) returns (ypresp_key_val).
+ * gets the next key/datum from the map.
+ * YPPROC_XFR takes (struct ypreq_xfr), returns (void).
+ * tells ypserv to check if there is a new version of
+ * the map.
+ * YPPROC_CLEAR takes (void), returns (void).
+ * tells ypserv to flush it's file cache, so that
+ * newly transferred files will get read.
+ * YPPROC_ALL takes (struct ypreq_nokey), returns (bool_t and
+ * struct ypresp_key_val).
+ * returns an array of data, with the bool_t being
+ * false on the last datum. read the source, it's
+ * convoluted.
+ * YPPROC_MASTER takes (struct ypreq_nokey), returns (ypresp_master).
+ * YPPROC_ORDER takes (struct ypreq_nokey), returns (ypresp_order).
+ * YPPROC_MAPLIST takes (char *), returns (struct ypmaplist *).
