/*
* 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.
