+ * consists of a single `*' character, INADDR_ANY is used.
+ *
+ * A line can also consist of just
+ *      hostaddress:
+ * where hostaddress is as in the preceding paragraph.  Such a line must
+ * have no further fields; the specified hostaddress is remembered and
+ * used for all further lines that have no hostaddress specified,
+ * until the next such line (or EOF).  (This is why * is provided to
+ * allow explicit specification of INADDR_ANY.)  A line
+ *      *:
+ * is implicitly in effect at the beginning of the file.
+ *
+ * The hostaddress specifier may (and often will) contain dots;
+ * the service name must not.
+ *
+ * For RPC services, host-address specifiers are accepted and will
+ * work to some extent; however, because of limitations in the
+ * portmapper interface, it will not work to try to give more than
+ * one line for any given RPC service, even if the host-address
+ * specifiers are different.
