/*
 * This code is such a kludge that I don't want to put my name on it.
 * It was a ridiculously fast hack and needs rewriting.
 * However it does work...
 */

/* The original idea was to put all the driver code
 * in one place so it would be easy to modify
 * but as hacks got thrown in it got worse and worse...
 * It's to the point where a user would be better off
 * writing his own driver and xebec should JUST produce
 * the tables.
