+* Description:  This header file contains the function prototype to the
+*               primary interface function for the XSVF player.
+* Usage:        FIRST - PORTS.C
+*               Customize the ports.c function implementations to establish
+*               the correct protocol for communicating with your JTAG ports
+*               (setPort() and readTDOBit()) and tune the waitTime() delay
+*               function.  Also, establish access to the XSVF data source
+*               in the readByte() function.
+*               FINALLY - Call xsvfExecute().
