+ * Create ticket takes as arguments information that should be in a
+ * ticket, and the KTEXT object in which the ticket should be
+ * constructed.  It then constructs a ticket and returns, leaving the
+ * newly created ticket in tkt.
+ * The length of the ticket is a multiple of
+ * eight bytes and is in tkt->length.
+ *
+ * If the ticket is too long, the ticket will contain nulls.
+ *
+ * The corresponding routine to extract information from a ticket it
+ * decomp_ticket.  When changes are made to this routine, the
+ * corresponding changes should also be made to that file.
+ *
+ * The packet is built in the following format:
+ * 
+ * 			variable
+ * type			or constant	   data
+ * ----			-----------	   ----
+ *
+ * tkt->length		length of ticket (multiple of 8 bytes)
+ * 
+ * tkt->dat:
+ * 
+ * unsigned char	flags		   namely, HOST_BYTE_ORDER
+ * 
+ * string		pname		   client's name
+ * 
+ * string		pinstance	   client's instance
+ * 
+ * string		prealm		   client's realm
+ * 
+ * 4 bytes		paddress	   client's address
+ * 
+ * 8 bytes		session		   session key
+ * 
+ * 1 byte		life		   ticket lifetime
+ * 
+ * 4 bytes		time_sec	   KDC timestamp
+ * 
+ * string		sname		   service's name
+ * 
+ * string		sinstance	   service's instance
+ * 
+ * <=7 bytes		null		   null pad to 8 byte multiple
